I have a very weird problem with my PPA.
It has a V1.0 PCB and Glassmans diamond buffers, power supply is a Mascot 2083 linear regulated.
Since some weeks the amp sometimes doesn't power up when switched to on. When I try some time later it works fine again. It never fails when it's already on.
Today I had the same problem again, and I searched for loose contacts, but couldn't find one. I tried to measure voltage between V+ and V- of the buffers and in the moment I touched the buffer's pins with the multimeter's tips, the amp powered up and worked fine again.
Is this problem caused by high rail capacitance on the amp and missing protection diodes in the power supply? I sometimes read about problems with this constellation, but didn't really understand what problems can occur.
If so, can this cause any harm to my ppa or to the power supply?
