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 ...

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 :-)

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 ...

Click the image to open in full size.

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 ...
