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.

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

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.

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.
