I need them for a 75TH too... haem ... I have your 75TH/300B schematic just on my desktop. Nice job Ed, congrats. JJ suggested me to use SMPS for my 304TLs but at the end I used CLCLC filtering so I have no experience at all with those boxes.

What frequency shuld I look for? I find a good source of SMPS switching at 27kHz... that seems to be quite close to the audio band (?).
