I really like the homemade look and I can’t see any reason why it shouldn’t work well. Is that Kevin Gilmore's layout you have used? Isn’t the tubes sticking out on solder side? More pictures, please.

Great, well done. Next amp in sequence?

Beautiful. Amazing work. ..and really like the "remote" power switch and volume control. Nice.

I don't know - I used a PSU with external heat sink. Maybe Eggil or some other Megatronist can answer that.

42 deg C (107 deg F), temperature raise 20 deg C (36 deg F). Heat sinks are Modushop 200 mm x 80 mm, voltage +/-500 V.

After reading Walt Jung’s article Audio Current Regulator I think there are reasons to believe that the original output tube CCS has better performance than the 10M90S CCS. According to the same article one can believe that cascoded 10M90S CCS is better than not cascoded.
