Alright then.

P.S. This PS1 looks conseptually like a MOSFET MAIDA as I had mentioned in a previous post. The M-MAIDA uses an Enhancement MOSFET IRF840 and LM317T. In this one the HV shielding component is a Depletion MOSFET. IXYS one. The reg chip is a low drop out 3A. Stick 1K stopper resistor where it says G if it will give you trouble again in another application. And/or exchange the IXYS with a Supertex DN2540. Make sure its insulated to its sink. Having no direct experience with that reg, just a guess.

then use some of shunt regs floating around

believe me - mucho better than series

disclaimer - no commercial interest in shunts floating around

(after all - if you make it by your self , nobody will have commercial interest )

HV shunties are sensitive and dangerous items to muck about much with btw. Smoke on the water, fire in the sky.
(Although all the guys who made hardwired shunties for this pre got them right, but they are expert builders).

Don't do it, they mess up together. Try FT-3 bypass for fun at a point.

OK, I rephrase, ''expert builders plus one expert in building schematics but not in tweaking them''.

Im the snake charmer at Camden Market. I just talk about the snakes but I never show them. Actually the dusty 6V6 plank found her self a new plank today. Gonna see what a proper linear setup can do. Got a new pair of 99 dB speakers with Faital 15XA38Nd pro elements home today. Gosh it was emberrassing to hear every scrappy detail of the rest of the soundchain.
