    Kenwood KR-5400: one channel distortion

    Hi all, I have been working away on a Kenwood 5400 with one bad (left) channel: there is a variable amount of distortion at higher volumes. Pots and switches were checked and cleaned, power caps were measured and seemed OK (for now). The signal going in the power amp is clean: I measured a 100...

    Troubleshooting: I have isolated a problem resistor, but the issue lies somewhere down stream

    I'm new to hifi repair and have become really engrossed with it's puzzles. I found a Technics SA-101 on the street last week and took it home out of curiosity. I need to give it a deeper clean but I don't think that's where my issues lie at the moment. When I got the amp, the right channel was...

    Sansui's Moody Blues

    Hi there, I have a nice and mellow Sansui AU417 but it has become temperamental i.e. it's happily playing both channels and then the right channel becomes suddenly & randomly distorted, so that I have to switch the balance knob to the left side only. This lasts for different lengths of time, and...

    CR-420 with left channel distortion

    So I've cleaned this guy and replaced all the capacitors in the power supply section. I thought I finally had it working and it sounded great on headphones. I hooked up some speakers and it initially sounded good, but I've started to get an intermittent distortion only in the left channel. It's...

    Asymmetrical amplifier output on sine wave - LR-1500TA

    First of all, still learning things. That said, I have a Lafayette LR-1500TA that works - for the most part. I've recapped it and deox'd it. Gone through bias current adjustment and balanced the voltages. It sounds fine, up to mid-level. At some point as I raise the split-volume control...
