The base of the case is a recycled switching supply case used in communication, very rigid. I used good quality parts, Mundorf main supply caps, Cardas connectors and wires for power, 6N single crystal/TFE wire for signal, AMP gold plated power connector, Vishay and PRP resistors, Wima, ROE caps, etc.

Thanks for your comments.
RA7, I did a few years back a two parts article on how to make your own PCB.
Files are kind of big. Send me a private email and I'll send you a copy.
I used to solder plate my pcb, now I used my ''special'' sprayed protection film to protect the copper. What is great about this stuff that is burn away when you solder the part. No need for a solder mask. For small smd parts, I install them first, then spray the stuff, finally I solder the bigger through hole parts.
6L6, I got the R-Core transformer from DIYclub, part R26-75, paid U$19.25 + shipping at the time...

Nice Sylvain, I wish I would have seen those R cores when I bought mine labled 2x24 that turned out to be 28 VAC that put me at the ragged edge of the max for the regs.(40 dc)
What regulated DC voltage did you wind up with their labeled 2x20? I,ll bet it,s off but Nicely in range🙂
I might switch to these to get rid of a small variac I,m using to keep it in range,.. its not optimal but works for now.

These transfo from Asia are for 110/220V, we have 120V in North America, giving us some more voltage. I don't have the exact figure but I do remember it was plenty. I'll get the reading tomorrow.
