Symasym - the sequel

[AAK]

As far as the jfets. I believe that it should work, but without trying it myself I can't tell you for sure. Somebody else out here, maybe Roender, can be of more help.

Your question about the advice provided post #116 found here.

All of it was incorporated into the current design found in sa50d.zip.

I'd like Al's board.

As I'm doing monoblocs.

Ryssen,
You might want to check to make sure that everybody is in agreement to which board there going to get. There was some question whether to build mine, or Mike's version 5.3 which has been heavily tested.

Ok,so to be sure,there are no misstakes.What board did you sig up for?
I signed for AAK´s board.

 

[Colescuttle]

To be sure, AAK's board for4 me.

Hummed to the tune, "Anticipation."

Hmm.the GB is on hold..
Waiting for adress from AAK and PeterA.
And Peter M and SteveA to confirm that they want AAK´s boards.🙂

AAK is it right that your Boom is compatible with the Symasym 5.3 schema?
I have sent a new price and shipping question to the Pcb maker,wile waiting for this things written.
🙂

Hi,

I've been thinking about Symasym for a while, I might be interested in PCB's for 6 channels if the price is right, but I'd like a version of proven stability and performance... so I am a bit confused here.

There appears to be a PCB group buy for Symasym, but there are two different versions of it, one of which is / is not a monoblock, and the schematic is / is not identical to Mike Bittners V5.3? And pricing is not determined as yet?

 

[AAK]

Hi Ryssen,

Yes, my bom is compatible with Symasym's version 5.3 schematic.

Al

 

[Ryssen]

Ok,that does it..😉 Then we have a confirm that Symasym 5,3 schema and AAK Boom and PCB´s that this GB is about,will work!
I got prices from the pcb maker today if we order 30 pcb´s the price is
15,30USD(according to Forex) a peace,and the shipping to ME is 18 USD,then commes a paperbag(or envelope)1,4USD and the shipping to your country.

So...Waiting for adress from AAK and PeterA.
And Peter M and SteveA to confirm that they want AAK´s boards.
🙄

And MBK If you think the price is tight,I think it is😉 and you can use the
rectifier and e-lyts on the board or not.Or one PSU for 6 channels if you like.🙂 Tell me if you want some boards..

 

[MBK]

Hi Ryssen,

still thinking if size and total cost (components, availability etc) are feasible for me. This is for active speakers, 3 channels per side, with this pcb this gives me some redundancies (the PSU) that add size. The PCB price seems good.

One suggestion - whether I'm in or not - you might get a lot more interest if you make a "Symasym PCB GB" thread with the vital infos on it and a sign up wiki page. I'm sure many ppl don't even know that "The sequel" has mutated into "The GB" 😉 So with another week or two sign up time for people you might drop the PCB price even farther, prompting others to buy spare PCB's etc. Just a thought.

 

[Ryssen]

Hmmmm,😉 Thank you Peter M for your confirmation.
I just found out from the Pcb maker that the prices I got was WITHOUT VAT,so the real price for one Pcb is 19,12$ 😎 shouldn´t be an issue,or?(Thank you Sigurd for reminding me.)
I can start a threat in the GB thread,If no one is in a desperate hurry to get the boards?Seems I (we) have to wait a while anyway for all the confirmations and adresses..🙂 And a short description.But the Wiki page just ain´t my cup of tea,so unless sommeone else does that part I will go on the way I started,Notepad..🙂
I will move this GB and will post a link later.

 

[rephil]

Hi Ryssen,

At 19,12$, it is OK. I am in for two more boards. Check your Email box ! Total number of boards for me : 4.

Best regards

[Colescuttle]

ETA for boards?

Hi, Ryssen:

Good move to do a GB for Al's PCBs; I see you currently have commitments for 54. Do you have any idea when you will end the GB and process an order? My schedule gets very busy during the Spring and Summer and I'd like to build in some free time to get my monobolocs finished.

Thanks.

George

 

[Ryssen]

Been thinkin´ about that to..
You don´t mind if I write the last date in the GB thread?

 

[Colescuttle]

Date in GB is fine.

And I don't mean to push as I really appreciate you doing this. In fact, would you like a payment up front, so you're not operating out-of-pocket? PayPal is probably the easiest and most direct way, and you can add a percentage to the total so you don't get burned for the PayPal processing fee (I never remember to account for that when pricing things to sell).

George

 

[Ryssen]

Paypal is nice for most of us,but some prefer or have no option to banktransfere.
When I send the files to the pcb maker I will ask for the final price and the shipping to me, and calculate the final sum.And uppdate the xls.file.
How much is the % at paypal?
And the date,if anyone thinks we should wait longer,we do that.🙂

 

[Colescuttle]

PayPal seller's fee.

It appears that the seller's fee is a bit above 4%. To be safe you could add 5%. Not much of a commission, but you could cover some of your costs.

 

[Ryssen]

Ok,thanks for checking that,I will add 5%.

Guys, can you keep the GB stuff in its own thread please.
