What tests do you want done? 🙂

Thx-RNMarsh
Richard, did you start assembling?
by the way, nice gear.

Not yet... I would have to find your schematic and bom list, first. then start collecting parts.

OK, here is last schematic and last BOM, to make it easier for all builders.

Hi dadod is on your plan to share pdf pcb for this ampli.?OK, here is last schematic and last BOM, to make it easier for all builders.

You can easily make your own layout from the picture here. http://www.diyaudio.com/forums/solid-state/235695-no-nfb-line-amp-gainwire-mk2-25.html#post3799212
I could share the pdf when I see how is going with those 20 PCBs first

Had a look at the BOM and have most components already.
Do you have alternative parts for the DN2540?

Sorry I don't know any alternative part, this is depletion mode mosfet in TO220.

No problem. Shall hunt some of these out. I think Mouser do them.
Want to build this exactly as the designer meant it to be.😉

Those depletion mode mosfets from Supertex could be used for many good things, CCS is first to come to mind, but excellent for a buffer, in simulation shows very low distortion, but I never built any(for now).
ps. I think that you can use DN2535 in to-220 package too, just check how much source resistor you need to get 100 mA ccs current.

Hi Dadod
there are multiplied part on the schematic and BOM, for example C11, C12

Thanks Pawel, I will check that and correct soon, sorry for that.

I am very sorry for those errors, some I corrected with added explanation in the BOM, because some are printed as silk screen on the PCB.
I hope this is not going to provoke confusion. When you start to assemble, ask if something is not clear.
