Hello,
I thought I would post this here since a lot of you use pots with you chip amps. I am trying to organize a group buy for the new PEC pots that Peter Dainel so highly recommended ( found *HERE* ).
There is one place I found that sells them for $50 + $7 for shipping ( found *HERE* ).
So far I'm looking at a stereo pot, 10% precision, 10K ohms, log taper, SS shaft & case, with gold plated terminals. We need to get 30 for the price to be ~ $37. Shipping ~ $5 which = about a $15 savings. If we could get 50 or 100, the price will be even lower!
Let me know what you guys think as well as any suggestions. I may also be able to break up the order such as 15 x 10K pots, 10 x 20K pots, & 5 x 50K pots... you get the idea :)
Thanks,
-CHRiS

I'd be interested a group buy, but can we get a discount price directly from PEC?
I'm not sure about the spec of the stock pots, but looks like Brian Cherry may have specced tighter tracking tolerance on the ones he's selling.
Anyone have tracking problems with these?
Also, I'd be more interested in the 1M value for use with a faking resistor, myself.

I called Electrosonic and KK pots are available from them:

http://www.e-sonic.com/acc/products...2fPotentiometer
10pcs price is $27.60 and when you go over 40 pcs. the price goes down to $22 . The lead time is 1 month. All prices in CAD.
When I called PEC, they quoted me $80 for a single pot and something like $40 for 10 pcs.
BTW, both PEC and Electrosonic are located in Toronto;) |

Hi Chris,
"Let me know what you guys think as well as any suggestions. I may also be able to break up the order such as 15 x 10K pots, 10 x 20K pots, & 5 x 50K pots... you get the idea"
what about other value?
Hi Peter Daniel,
beside the 50K Log that you try, have you try other value (10K, 25K, 100K, 250K) and type (linear/log) and faked linear pot?
What do you think about 500K linear pot + 22K law-faking resistor (as available on the Brian kit) will be good?
I see that Mr. KYW suggesting law-faked linear pot will be better than log one, and he suggest highis valued pot...
Actually I'm worry whether my CD player (Meracus Tanto, which only has 1.2Volt output, not a common 2.0Volt) will be able to drive such a high value... (500K or 1M)...
Thanks,

| I tried 25K log and it worked fine with GC amp. I have no experience with linear pots and law faking resistors. I'm also scared by high series resistance in such applications. |

I switched to PEC pots a little while back. I bought 5 25K mono log pots at 9 something each. Was able to match 2 exactly, and two more at 100 hms, which is 0.4 %. The two used seem track perfectly.
I really wanted some 50K stereo log pots to parallel to make a 25K mono pot. The the mono pots seem to work fine. I think to get a good match it will require purchasing a handfull of stereo to get 1% match.
As a side, the taper on these is different than others tried. It is much more gradual on the low end. It is the exact opposite to the normal hair trigger pot. But once past about half way open the volume comes up fast.
I really like mono pots. With my DIY skills the ability to shut off one channel to locate a problem is handy.

Hi Peter,
which one of the 25K log and 50K log is better? On Brian's GC, as a passive...
also when you try pot (both pot cases), did you remove/unremove the 20K/22K (R2) shunt resistor?
Off topic, I found that on the schematic (as on Brian's nigc_kit-users_guide.pdf) the R2 is placed (shunted to the ground) in front of R1 (grid stopper? as in tube amp design to reduce oscillation?) while on the board, I found that R2 is placed after the R1. Is there any reason for this?
REgards,

David |

|
| Peter Daniel |
I believe there is a mistake in a schematic, as the shunt resistor is preferred to be after the series resistor.
25k version is better choice for GC. I still use 22k shunt Caddock, as it sounds better to me this way. |
|
|
| dw1narso |
Hi Peter,
25k pot & 22k shunt... means totally closer to the 10K pot then?
Regards,
----
David |
|
|
| Peter Daniel |
| I guess so. I'm using 22k as I have a stock of them. If you worried about low input resistance you might go higher with shunt resistor (50k or so) or not use it at all. Initially, I didn't use it, but preferred the sound when shunt was installed back in. |
|
|
| dw1narso |
thanks then... Peter...
maybe I should hunt for available various cheap pots locally and try the combinations by myself before change it with a serious one... like PEC
(I say "hunt" because in Indonesia, DIY-ing is very uncommon. It is very difficult to find linear pots and pots of smaller values like 10K or 25K. Even toroids, I have to buy from Singapore...)
I'm going to open a thread regarding my burning in GC experiences and questions that I will sure need your help again... I wonder whether the pot is part of my GC experience/problem...

KT- "I'm not sure about the spec of the stock pots, but looks like Brian Cherry may have specced tighter tracking tolerance on the ones he's selling."
Where are the ones Brian Cherry has for sale? I think PEC only specs 10% & 20% ones.
Peter-"When I called PEC, they quoted me $80 for a single pot and something like $40 for 10 pcs."
That's exactly where I got the price for 30 pieces. I thought it wasn't bad compared to the $50 ones but after looking at some other sites I would think it would be better.
dw1narso-"what about other value?"
I can get others as well. Let me know what # values.
-----------------
Panelhead - That point has been brought up about buying mono pots from Digi-Key since they are ~$10 & matching them but you found out 1st hand the down side to that :)
Peter - Do you think the 25K would be better for the GC's?
Thanks guys & I'll keep checking on them!!! :)
-CHRiS |
|
|
| Peter Daniel |
| You mean 25k vs 10K? It's hard to say, some recommend 10k or even less. But I prefer a bit higher input resistance (especially if the pot is in parallel with 22k shunt resistor). Would be interesting to compare though. |

Cdoggy,
Brian Cherry sells them at DIY HiFi Supply:
http://www.diyhifisupply.com/diyhs_dact_switches.htm
Here is Brian's quote about the tolerence. This is what I was referring to:
"These are specially ordered with 10% tolerance (standard tolerance is 20%)."
Does someone sell them stock with 10% tolerance? Looks like Electrosonic does from the links Peter provided.
If a group order is put together, I'd be interested in the 25k and 100k log pots. If any 1 meg linear tapers are ordered, I'd be interested in that, too.
Electrosonic seems to have the best prices. The KK pots are stereo?
KT |
|
|
| dw1narso |
| Yes... KK is the dual ganged pot (stereo)... |
|
|
| cdoggy81 |
KT, mine are 10% as well.
"So far I'm looking at a stereo pot, 10% precision, 10K ohms, log taper, SS shaft & case, with gold plated terminals. "
They come standard in 10% or 20%.
I'll talk to them tomorrow about adding a 25K log pot to the mix. |
|
|
| dw1narso |
I just notice that e-sonic only put linear pots on the list :
2RV7NYS????A
KKU????S64
and no log pot.... |

I need to get a good idea of about how many to see if we can get a higher qty discount. At a min, we are looking at 30 @ $37. |

Hi Chris,
are you sure do not want to contact E-Sonic?
their PEC pot is priced as follow:
1 @ 27.590
40 @ 21.960
100 @ 14.820
250 @ 16.790
and it is in Canadian$...

Yes I could, but the reason I didn't in the 1st place was because of one of your post:

errr...why is the 100 count cheaper than the 250? |
|
|
| KT |
I guess whoever is point person on the group order should give e-sonic a quick call to confirm the linear/log situation.
If e-sonic does in fact have log pots, the savings is substantial.
I'll have to check my values, but I'm in for 2 pots, either 2 100k logs or 1 50k and 1 100k log.
Thanks,
KT |
|
|
| cdoggy81 |
Ok, finally after 7 days I got a reply from e-sonic. Didn't help...
The rep told me that their part # is listed for both log & liner pots & it depends on what the mfg. sends to them. They have no way of knowing unless you can trace the lot# from the mfg. I'll still keep trying........ :confused:

Great to see things coming together
I just committed to building a Pass Labs Aleph 1.7 fully balanced discrete preamp, but need to check on that forum what values of pot will be best. From the archives, most people seem to be using 5k or 10k. So, I'm definetly in for both those two (stereo).
But, I am also interested in Thorsten/Kwei's suggestion of 1M law-faked pot. I guess that makes three for me.
I'll now later today and post a definite count.
Thanks for organizing this. |

Hi Chris,
I really want to join the group buy... But my current financial and my consience still hold me to buy a pot for US$37... (As an Indonesian, I'm paid in Rupiah, while Rupiah to US$ exchange rate is getting worst. I feel guilty to my family to spend such amount of money in the recent situation)
Sorry that I ask you to connect e-sonic. Cause for their price, I might still consider to join the group. But since as you found that they are very uncertain about the product that they sell, I don't think you will get from them by the time the group has been ful-filled.
So... I'm back off... maybe next time...
Cheers,

David,
I have only the deepest sympathy with your predicament and I will
request some extra PEC's to make up the shortfall and increase my order to :-
2 X 100K log stereo
3 X 50K log stereo
3 X 22K log stereo
2 X 10K log stereo
I hope this is Okay and whoever kindly ships does so as a 'Gift' and can take paypal,HM Customs are popularly known as the adulterated filth.
Thanks awfully. |

Now, the big question is.....do they make an 8-deck for balanced operation?
I suppose I could always use a 4-deck as was previously pointed out:

Hi IndyAudio,
fully thanks for your "sympathy"... I don't want to sorry for myself... Just I have to be realistic on my "limits" in my life... :)
Hi darkmoebius,
are you talking about the Precision Electronic Components (PEC) potentiometer (that is starded on this thread by Chris)?
I don't think there is 8 decks version, even not the 4 decks version.
If you check PEC datasheet, maximum is 3 deck version (which use KKK code).

Oh well, I was kind of hoping there might be a balanced version.
The balanced ladder schematic that I posted will work with the 2 deck version.

Thanks for spec sheet, I hadn't seen that before. |

Sorry for the confusion, but I'm still trying to figure out what would be best in my setup. Luckily we have time.

The KK will either be 10k or 1M. |

darkmoebius,
You will be better off buying the "K" series from Digi-Key. They are only $10 or so. (I still can't figure out why a mono can SELL for $10 and our COST for a stereo is almost 4x that??? :confused: They must buy one hell of a lot to get their cost down that much.)

Hello all. To clear up some confusion the price is going to be $37. The next price break is at 100 parts :( Atleast we hit our 30 :) I'm going on a ski trip this week so I will start finalizing this thing the week of the 3rd so we still have ~14 days to get all of our orders in. If we can get all orders in sooner I will order sooner. If this is too long let me know, but I just wanted to give everyone enough time. The week of the 10th I will start collecting $$ & place the order. I will keep it similar to Brian's Chipamp.com format with Paypal & flat USPS shipping rates.

| I'm a latecomer to this thread but I think given a little more time, we should be able to hit the 100 unit discount point and a price target of $20 delivered per pot. Given the purchasing power available in this forum, I think we should wait for a larger order/lower price. That said, I'm interested but I'll stay on the sidelines until you get the price down. |

Yldouright and Sbolin both have good points. More exposure and more time could easily double the value of this deal.
A second pot for 3 bucks makes a wait worthwhile. I'm sure at that price, many would double up their order. |

I'm a noob and the the chip amp forum, group buy, and trading post forums are the only ones I view. I'm sure if people in solid state and tube see something like this they might want to buy a few.
Also if the price went down to $20 (I saw someone say) if we get 100 then I'll buy two or more instead of just one. I'm sure others would agree to buy a few more for the big price break and the trading post forum is always a good place to sell the extras you buy. |

kestrel200, Appalachian Mtn is where I'm going. I'm quite excited! Never been skiing before so I thought this would be a good place to start. If I can do it & want more, next time we'll go for sugar mtn. Funny how we have ~ 300 acres in the mountains of Morganton (off 181 between Lake James & Table Rock) & I've never been skiing up there. Living in FL we do it on the water :D
Now on to business....
darkmoebius & moe29, the 5K & 1M may not be "doable" but the rep is checking on that. We may need to reconsider values or cancel out. All other values should not be a problem.
Here is a price break down:
30-99 = $37
10-249 = $31
250+ = $21
yldouright, If you want to wait until we hit 250 parts be my guest but I don't know if people want to wait that long. All I honestly was concerned with was hitting 30 so I could buy one cheaper & 29 other people could get a good deal. I want to help out as many as I can & I do see the potential for a larger order but again I as well as others I think don't want to wait forever to get their parts.
Like I stated before we have ~14 days (13 now) before I even do anything. I agree that it would be a great idea to move this or post another thread in the group buy forum. I'll see how this thing pans out & we will revaluate the situation when I get back on the 3rd.
Thanks so much to all who is going to make this possiable!

You already have 39 orders on the list and many of the members would double their order at $20. PEC is not the only place to source these parts and even if they were, I believe they could be persuaded to accept a $2000 order for 100 pieces. I also want to suggest that Peter Daniel recommends that pot with his highly optimized design but that doesn't necessarily mean that users varying from his complete parts spec will achieve the same excellent result. Part selection is a symbiotic process and there are other very high quality pots on the market which can be used in this application. Either way, I wish this venture a happy conclusion because all audio projects need good pots and the cheaper we can get them, the more likely our successes. |

I commit to one 25k stereo.
I agree- at around $25 the number ordered would double instantly.
Heck, everyone would only pay a bit more and get twice their order!
I would get 2 if the price lowered to under $30.
Also, how much cheaper is a mono pot than a stereo one?
Please shop the 100 quantity around- maybe the various sources will take us more seriously with that quantity.
At the moment I am using a 25k pot in my Brian GT gainclone, and it gets loud too quickly-my speakers are quite efficient. Because of this, at low levels the channel volumes don't track well at all. I believe I read here that these pots have a flatter curve at the beginning-right? also better channel matching- so I would be OK? |

| KT |
If we can get the 100 unit volume discount, I will be up for 4 or them.
Thanks,

After adding up all the parts/costs to build a fully balanced Aleph 1.7 preamp ( 88 0.1% resistors, 36 capcitors, 30 mosfets, 26 diodes, 8 rectifiers, 2 transformers, 4 pots) using premium components, I've decided to make the leap to a much simpler and more elegant solution - S&B TX-102 transformer volume contol.
I think it was the cost of premium capacitors and the frustration not knowing which brands to buy for which locations that pushed me over the edge. Way too many nights up late reading posts on everyone else's preferences and still having no idea what to do.
Anyway, thanks to all for putting this great buy together.
On the other hand, I'm about to spend twice what I was originally planning.:cannotbe:
Better be worth it. |

So when can a group buy page start, and maybe Wiki page?
I want to hear my half finished Gainclone ;)
here I think is the list, this is in hopes of 100 pieces so if we get the 100 piece price break please state if you are willing to buy more.

right?
Is anyone else up for adding atleast another one for a price break? |
|
|
| Variac |
Variac wants at least 2 if there is a 100 price break.
At least one at the current price.
I think that you have to find out what the best 100 price is before people will start increasing their orders. |
|
|
| Variac |
| Once you find out the best 100 price, then why not start a new thread in the Group Buys forum titled something like Order for PEC Carbon Pots at Reduced Price! So people that have already given up on these pots because they are expensive will take another look. |
|
|
| edjosh23 |
Variac, I agree we need a group buy page and a Wiki page, I'll create a group buy page when I have the time (school just started back up), but I'm a noob and don't know how to create a wiki page or anything.
Variac your welcome to start the group buy page |
|
|
| Variac |
I don't think we should start the Group Buy thread until we know the price for 100. The idea is that when we start the new thread we give new publicity to the buy- we could even put the new price in the title:
"PEC Pots now reduced to $25!" |
|
|
| edjosh23 |
| I think $25 is a little too hopeful, but I agree it should be in the other amp forums |
|
|
| edjosh23 |
| I didn't even know there was already a group buy thread about the pots here |

KT LMK if it's going to be 50K & 100K or both 100K.
moe29, LMK if 10K will work or if must be the 5K. (Pass stuff I take it?)
newbie88, wyomitch, planet10 LMK as well.
I have been getting some emails about payment & shipping. I will take US money orders & paypal. Don't send anything yet. Shipping will be a flat fee like on the www.chipamp.com page, $6 us, $11 int.
I also want to know if the 18 of you want to wait & see if we can get to the next price point or go with the order now. If your name is not on the list I will not listen to your reqest. These guys are committed & they are what matters now. Thanks to all who made it happen! :D

cdoggy81,
Please change my 100k pot to:
100k Stereo *linear*
Thank you.
BTW: I can wait for a while if folks want to keep the offer going to try to enlist some more buyers. Doesn't look like to many buyers added in the last few days though. |
|
|
| sbolin |
| I vote for waiting to see if more buyers show up on the group buy thread. |

OK,
If shipping International (The Netherlands) is $11,- , I would like to order one 50K Stereo log pot. Payment tru Paypal

Just to clarify,
I would guess that the weight of these PEC Precision Series KK's is about 3 ozs. ? and just to clarify the situation unless there are favorable combined shipping charges;please include me out.
This is not a proviso but I have absolutely no intentions of wasting $110 USD shipping on component s' which will advantageous to buy in the future' and whose shipping costs should be a fraction of,I'm in no hurry.

My guess is "flat rate" 11$ is for all ten pots....don't get upset yet.
Might actually be a good deal for you. :) |

I'll happily wait to see what the 100+ price is...

Chris,
I won't be starting my new project for some time and my current Gainclone sounds good so I can wait. I defer to you though.

Hi all,
Is there a firm date for a deadline? At this price point, I will be going for 2 of them, one is a 50k and I have to check a schematic for the value of the other one. Please let me know when the final date is and I'll have the info before then.
Best,
KT |
|
|
| Variac |
Boy, it sure is annoying seeing them listed at $21.96 at e-sonic in quantities of 40.....
I wouldn't mind linear at all, but we need to get different values if they are linear in order to do the law faking stuff. This is driving me crazy!
I they would just find out what is available to them we could order- and cheaply!! |
|
|
| KT |
I'm a bit uncertain as to whether all of the vendors have been contacted or not. Seems there's some confusion as to which vendors carry what version of the pot and for what price.
Should everyone post the information of the vendors and part numbers they're looking at so the organizers can get a complete list of everyone they should contact? Is there an easier way of doing this?
Anyhow, when the group order happens I'm up for a 50k log, as stated earlier, and then a 100k log as well. If I have the funds at that time, I may get either an additional 100k log or a 1 Meg linear. But two, for sure, at this time.
Best,
KT |

As you know, I have contacted various suppliers.
Here is an interesting response:
Quantity Description Unit Price
100 Potentiometer Model KKA2531S28 US $22.60
Log taper, 25,000K ohms, resistance tolerance 10%, slotted shaft, 7/8” length
by .25” diameter stainless steel shaft, dual ganged.
Quantity Description Unit Price
100 Potentiometer Model KKA2531S28 US $26.95
Log taper, 25,000K ohms, resistance tolerance 10%, slotted shaft, concentric
shafts, dual ganged.
Delivery : 4 weeks ARO.
Terms : Net 30 days upon credit credit approval. VISA & MASTERCARD
Special order item, non cancelable, non returnable.
I love the idea of concentric shafts.
They have an option for concentric shafts- with the right knob set this is the perfect solution for balance. If both knobs are the same diameter, it is easy to turn them both at the same time. If the balance needs tweaking-then carefully turn one.
I know where to have a set of knobs for concentric shafts made!
I realize not everyone wants 25k pots but I'll bet half of the people do. I can enquire about other values!

Digikey can special order these KKA 25k (or others) pots also, but they are more expensive, unless you order 250 of them, where the price drops to $14.88 each. 50 unit price is $28.55 each

Turns out they gave me the wrong pricing the first time. Here is the correct pricing for the KKA 25k pot from Digikey (asked for the KKA2531R16)
20 $51.87/each
50 $28.55/each
100 $21.57/each
200 $21.57/each
250 $14.81/each
So it looks like Digikey would be a good source to purchase the pots from. I am checking into the 2RV7 version of the pot (military version of the same pot in the datasheet) and will see what the pricing is.
