Then the external power supply. I used a small hammond steel enclosure. I prefer steel for the supply for increase shielding. Everything is mounted point-to-point.

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.

And the case finish. To cover the sides [I] used small slide of wedge wood, with oil finish. The rest of the case, front, back and top were done by Front Panel Expert. Exquisite fit and finish.

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...
