Channel balancing issue
I have this Sony TC366 that I'm slowly resurrecting. Current issue is the right channel seems much hotter than the left. I initially tried recording tapes myself and the right channel sounds fine with the left sounding muffled/as if a low pass filter were put on it. Figured that either the tape could be bad or too old or the heads are beyond the end of their life. Then I got a prerecorded tape and the right channel is maxing out the VU meter most of the time with the left seeming somewhat normal.
I've adjusted the heads and cleaned them, sprayed contact cleaner in the switches (although maybe not enough), etc. Could the culprit here be a bad capacitor on one of the amplifier boards? High gain with a prerecorded tape makes me think it's something electronic and not just a corroded switch or knob.
