I am about to make a small run of 10 PCB's, and i make layout i prefer !
Here is photos :
ImPASSe Schematics,
InPASSe PCB - TOP,
InPASSe PCB - BOTTOM,
InPASSe PCB - COMPONENTS,
InPASSe PCB - ALL,
And here is OSHPark Render of TOP and BOTTOM side,
Board is optimized for JENSEN Transformers ONLY, and for Mundorf EVO or MKP series capacitors, also bigger resistors are in size for KOA or Panasonic sizes ...
Boards will be about 9" x 4" 2mm thick, HI Temperature grade, 2mm thick, and double thick copper, Immerson Gold finish and probably Red color ...
Thnx !
Any comment and point on mistakes or improvement is welcome ...

Hi Komigenie
Sorry but Pass Labs logo is copyright trade mark.
Please think about respect of this that be cool pcb´s
but without typical Pass Labs fonts imitation 🙄
Very nice layout !
What Your point of view ?
Kindly regards 🙂

Why don't you start a GB thread, I think many people would be interested(me including 🙂. This will help do drop a price a bit. Very nice layout indeed!
No, i am not trying to run group buy, is like test run, i want to build preamp for my self, and few more guys who will be interested, and if everything come out OK, boards prolly will be in DIYAudio store !
If no one want to join this test run, no problem, OSHPark will make 3 boards for me any time ...
I just need few more eyes to see possible mistake on PCB, and or some suggestions on layout and component sizes ...
Thnx for suggestion 🙂
I ask Mr. Pass about logo, and i have permission to use ...
He is great again, like he always was and always will be ...
I made few changes on the board, and here is final rendering:
TOP of the PCB,
BOTTOM,
Transformers, Inputs, Attenuator connection, etc ...
PSU on Board, i moved chassis pins on the PSU area, who dont want to use metal standoffs but nylon, there is wirepad for grounding chassis ...
Places for Tube Sockets, under 6SN7 is screw hole for [M3 standard screw size] for preventing PCB bending while inserting tubes ...
I am still going thru PCB to find possible errors, and soon will order ...

OK, here is final design, going for production in next few days !
This 10 pieces run is just for friends, and please dont ask me for Group Buy!
Will be for sale, but not by me ...
Thanx !

Well, i go for Mullard this time !
Mullard ECC33 - NOS - date code indicate manuf. date March 1953 !
iA1=9.2mA
iA2=9.0mA
