Those be the one max..You set them for 300vdc.Also,don't use the kt66s there..You can but its silly and I would use the 6n3c-e that we talk about as thats what was in it originally,at least the ones I got in..
If the power supply waveform isn't pretty,neither is the sound in most cases.

  Mine came with Sovtek "5881" as regulators, which are not really 5881s at all, but 6l6GCs. I tried NOS Tung-Sol 5881s there and thought it was an improvement, then I went with the Sovtek KT-66s (as recommended by Mick, the designer) and they sounded better than either of the others, with fuller sound and more overall sonic impact.
  
  Thanks for the info on the adustment pots. I'll make sure those are dialed-in correctly before I start on anything else.
