Hi, i am almost new to electronics. I have soldering gear and humble soldering chops.
I have recapped a circa 25 years old stereo compressor (Estec Twincomp) using Nichicon KZ capacitors of the same specs, to replace original Thompson capacitors. I did only the audio board.
It was sounding fine at the beginning, just felt that the signal lose a tiny bit of "size" if that makes sense, when passing through the compressor (subtle difference). The task looked easy so i decided to try with expensive capacitors.
Once finished, the compressor exerts a constant hum, which frequency variates (basically making weird noises) if i inject audio. I have examined the board but it looks fine.
So i don't know what to do now... i heard from the previous owner that the designer himself, Sonny Schneid, told him that if he was to build again the compressor he would have used Panasonic FM. So i am tempted to give it a try replacing the Nichicons with FM, but do not know what to solve this hum problem...
