I recently accidentally shorted out the left channel on my CR-220 and didn't realize it until my nose told me so, followed by major distortion of the high end on the left channel. It also seemed to be getting very hot :/ Now, if I only have headphones plugged in it sounds okay at low volume, but when I switch the speakers on it's very bad. I've scoured the schematic diagram and board layout and am thinking about re-capping all of the electrolytics on the left channel (I think about five caps total.) What is the likelihood this is the cause of the fault? Should I plan on replacing any other components (such as ceramic caps, transistors and/or diodes, or even resistors or that little inductor?) If I replace components on the left channel, should I do the same to the right channel just so they're identical? I've done some work on this amp already, but only to replace the lamps on the tuning indicators (which have subsequently burnt out again.) Also I've re-capped and restored several old computers, so I'm excited to get my hands dirty on some audio equipment. Thanks in advance!
