(one more) ALEPH P 1.7 clone

I think you got GOLDFEEVER

Gold don't sound better, is not better for soldering, why gold?

me too, me too

I'd like three sets of boards.

About AP 1.7 with two supply boards - this means new production documentation and higher price. Probably it will be cheaper to buy 2 sets of AP1.7 in present version 😉

So all we need now is permission from Mr Pass - this is his project. I only designed PCBs basing on it 😉

No problems on my part.

I'm interested in two sets of tinned boards

about the partslist, is there someone who can point to it? I seem to have some problem navigating Passlabs page

Hi,

I am interested in a complete set of tinned pcb.

[urosh]

I would also be interested in one set of pcb's

nice!!

Hello,

I would be interested in getting one set of the gold boards.

If it turns out that you end up getting the tin boards, I'd still would like to purchase one set of those, so count me in.

I'd prefer gold, though.

Best,
KT

Only listening is boring ....😉
I need a new DIY project, this is a nice one.

So i would, if still possible, go for
- one set gold plated
- one psu

Anyone know if there's a Go-Ahead from Mr Pass?

Hi!

If we get Nelson Pass Agreement, I update my order :

2 * P1.7 PCB
2 * PSU PCB

if not possible, i want as many 'sets' as necessary to get 2 PSU and I would prefer gold.

Perhaps It could be more acceptable by N. Pass if we just order PCBs (and no documentation...there is enough in Diyaudio.com).
In my humble opinion, this is DIY, so searching and understanding is part of the pleasure as much as building and listening.

Hi guys!
I also want 2 psu and 4 main boards in gold if Nelson Pass will make his appointment to us! I hope so! Teake.

Waiting for MR Pass permission I made some modifications on AP PCB's. I also decided to separate AP1.7 from supply board so dual mono is available now 😉

AP1.7 supply

An externally hosted image should be here but it was not working when we last tested it.

Great news, Veteran🙂
The boards look very nice😎

[SRMcGee]

Count me in!

I'd be interested in two complete dual mono stereo sets, preferably gold (4 psu pcbs, 4 preamp pcbs).

Taking a brief look at the pcb artwork, I got a little confused:
IRF610/9610's pinout is "GDS" (correct me if I am wrong), but here the gate resistors seem to be connected to the center pin.
Someone seems to have mixed up gate and drain - is it me or the board's designer...?

Everything is OK with the layout - my version of AP was tested by several people 😉 I draw transistors footprints above to show mounting holes and dimensions. Take a look at PCB from bottom:

So yor actual layout isn't identical with the one posted on the first page of the thread?

I attached a screenshot of that (early?) version, and that definintely has errors. R33, R13, R22 don't connect the FET's gate pins, as they should, following your schematic.
