Help with PSU for tube DAC output stage

luvdunhill · 1st May 2008, 03:33 PM

Hi!

I've found a differential-amp output stage topology that uses 12ax7 and 12at7 in a dual cathode-follower configuration that I'd like to try out. Looks like I'll need +230v and -40v and a pair of 12.6v heaters. Any recommendations on a simple solid-state power supply that would perform well in this type of situation?

Thank you!

Could you post schematic of the stage ?

I could give you some advice for all the power supplies you need.

What the -40V is used ? Is it necessary to bias the +12,6V heater supply to some B+/4....
