Steve,

I noticed in other noisier places that you seem to be getting ready
to put a Seth together. I also noticed that you had done a 6B4G
version a couple of years ago. Since I'm collecting bits for one,
prompted by a Magnequest clearance of S240s a couple of weeks ago, I
thought I'd check in with you. I currently expect to build the signal
circuitry to the Mark II spec, but possibly do a different power
supply. I have several 500 VA step up/down power transformers that
would give 234 and 468 secondaries (AC), and thought I could use two
bridges to make the 320 vdc B+ for the 2A3s and around 420 for the
driver stage. It this excess complication without commensurate
benefit?

For those unfamiliar with this amp check this link:

I have a DAC to assemble before I start on this, just collecting
pieces now.

Thanks,

Skip
