Hi everybody.
I just found out that there aren´t any pcbs left at passdiy so I thought it would be a good idea to order PCBs.
If anybody is interested I could order more PCBs and make the price fall.
I need to know how many people are interested in getting PCBS so I can ask for a price offer.
Also I could organize a group buy for parts or maybe for a Parts KIT.
Just post if you are interested.

well I haven´t yet done anything and there isn´t much interest.
I am not even sure if maybe the Aleph Ono is better.
Does anybody have an X-ONO circuit maybe?

Promitheus,
I have heard that the Ono is a nice phono amp indeed. If you would like boards (power supply and gain board) I believe that Bourke (Username: Bakmeel on DiyAudio) has some left over from a group buy. They are very well documented also. I have a pair and it will be my next project. Email him or go to his website.

Hi ,
Is there still a possibilty of getting these Pearl boards made again?
I need one and looks like someone else posted today looking for a bunch of them!

Well I wanted to organize an order but the files from passdiy dont seem to work.
If the right ones are posted I would be glad to make a large order and distribute the boards.

Hey I just checked and the files for the Pearl Phono stage work.
If anybody is interested please tell me how many boards you want.

Hi
I would mabye be interested in 4 boards, but what pricerange are we talkin here - I se that Olimex will make doublesided boards for 26 USD each - do you think we can get under that ?
Cheers !

I will be back tomorrow again with prices.
I think it will be around 20-25 Euro a piece but thats a general price.
Like I said I will be back tomorrow with a definite price.

The cost of the board is around 15 Euro each thats around 19,5 USD.
What other parts would be good to be offered. Maybe the 2sk389 and the 2sk170bl?

I must say that sounds appealing, 15 euro is a nice price I think. I assume that it is good quality fibreglass, plated through holes, and so on ??
You may sign me up for four (4) boards - what are your time horizon on the end of the group buy ?
The Q's would also be a good thing to offer - here in denmark, ztx450 is hard to obtain, vs. 2sk170 (not BL) and 2sk389 is obtainable.
But, the advantage would be if prices could be lowered if many Q's was orderd at the same time ??
What do you estimate a complete Qpac would run to ?
Cheers !

The quality is like the original boards. Double sided with contact through holes, solder stop on both sides and component print on top.
1,5mm pcb.
What was in the Q pack inkluded?
The transistors only or what more?
For the 10uF PP caps I would propose 10uF 400V MKP-QS Audyn Caps from Intertechnik. I use them all the time and they are one of the best caps around. They cost 3,87 Euro but I think I could get them for 3,60 Euro.
Well I have to wait 1-2 weeks and than its going to take 2 more weeks at least till the boards are ready. so I guess if all goes well I can start sending the boards next month.

Just thought I would give you this link on Jfet matching.
Seemingly a delicate operation😱
Only the 2sk170's needs matching.
The Q-pack contained the transistors and the Zeners.
Also I will just mention that the Pearl boards from Pass, had a groundplane on the entire pcb.

Pearl boards ?
Jaume, I think you would want two boards, as I se it, one boards contaions one channel, so for stereo, you need two boards. I orderd four boards, as Im making a stereo RIAA for my self, and one for a friend.
Promitheus, i assume, that when it is the original gerberfiles used from Pass Labs, the surface would also be groundplane on your boards ?
I didnt know that the 2sk170 needed to be matched !!! - this is a real bugger I think, as it requires some skill - is it something that you could do - against payment of course - so that a complete Qpack could be offerd - with matched transistors (2sk170) ?
Considered the skill needed to match the small fets, I think this groupbuy would have the greatest appeal if a matched Qpack could be offered.
I think the specs on the board looks fine - and the time schedule is also good.
The 10uF I think, is not as vital to offer, as most people use crossover components, witch is available in I think all parts of the small world.
But again, 3,7 Euro (dont you call it "teuro"...? hehe) is cheap.....
cheers

Buhl you're right. I need two boards for a stereo pre. Thanks.
From my viewpoint the more components that can be sourced the more interesting will be the kit. Sometimes I've ended paying more in shippments than in goodies.

So the q pack was the 2sk389, the 4 2sk170 (matched or unmatched?)
, the IRF610 and then one Zener.
Is that right?
I have a lot of 2sk389 and a lot of 2sk170bl.
I will be making quads for these boards.
I can organize the Qpack. How much did the q pack frm passdiy cost?

Promitheus,
I know that you're organizing a Pearl group buy, but I think the Ono is a much better phono stage. If you decide to produce boards for the Ono, I would definately purchase a set (depending on the price, of course!).

Ron

Pearl boards
The Qs used in the Pearl (one channel only) is:
- 1 pcs. IRF 9610
- 1 pcs. 2SK389
- 4 pcs. 2SK170Bl - matched in quad
- 5 pcs. ZTX 450 - if this device is not important, another N-chnl. device can be used, eg. 2N2222 ??
I dont know weather the Zener was included, but I have a hard time loacting it, so it would be nice if included.
Is the "BL" extention on the 2SK170 important - some have it, others dont - is it the same device ??
Another thing, my price on the 50V/10000uF is 4,8 Euro for a generic type - no panasonic or another fancy brand - and each RIAA needs at least 8 of the - three on each board, and two in the unregulated supply - that means that I will need a total of 16 of them = 76 Euros...... Do you have a source for those that are cheaper ??
What about the 3300 uF - they are 1,25 euro here, and 8 is needed pr. RIAA, witch means I need a total of 16 of them also.
I dont know what the original Qpack costed, mabye some of the other guys in the forum can remember ??
Cheers !
