I have a CPS2 here which had a bad supercap. I replaced it and reset the volume with power on button holding, but there's a horrible amount of background noise.
It's very possible this existed before the supercap was replaced as it was defaulting to maximum volume and at dB reduction steps 0db to 8db there's no problem. As soon as you reduce the volume to 10db cut, you get background hisses, pops, crackles, whistling etc that comes and goes erratically. Turn it up to 8db again and the sounds immediately cease.
Any ideas? It's certainly analogue in nature.
