I have installed the SSLV 1.3 UltraBiB circuit, if it is volum <9h, it sounds fine, but the volum> 9h has a slight boil, the louder open will boil more, ask the cause and fix.
M1 = 3P20, M2 = IRF530, CCS = 660mA, R9 = 1K, C2 = 470uf, C3 = 33uf (PanaFC) ?
Help me !

Does not seem like a PSU issue. Maybe you got a ground loop in the application. Search/revise grounding.

P.S. The manual says if C3 is Panasonic FC then use 100uF/50V. So do that substitution also in any case.

Thanks again to Mr. Salas, I have isolated the loop groud, and replaced 33uf = 100uf / 63V, the sound is excellent, superior to other power circuits in terms of clarity, detail, powerful bass ...
Very impressive

I had finished and breadboarded the design one to two months ago. Its CRT who's scarce this period so there is delay finishing the PCB details. Working on it on and off. But last time we communicated he showed progress, had got the guidelines right this time, and he is in final stages.
