Hi all
Amplifier in question is Pioneer SX410
It still has original coupling capacitors. Capacitors at power supply have been replaced by a technician and 1 or 2 others. It had a hum and one channel was distorting and fuzzy sounding.
I don't know if full tests were done but his view is if the original caps are still fine, leave them alone. I am a little worried about the coupling caps due to age.
The amp still sounds fine without issues but as you know, the worry.
Is there maybe steps I can use with a volt meter and with the amplifier switched on to test the tube socket pins and see that voltages supplied are correct?
I know it is very high voltage but I have a steady hand and will be careful.
