Hello. I have a Trio KR-3600 stereo receiver that I have had for while now. I haven't used it for a while but I tried using it yesterday and noticed that the left channel was really distorted and it takes much longer to "build" volume than the right side does. All the knobs and terminal connections have been de-oxited and I have done the following trying to get it to work: Changed the speakers over - still left channel is distorted. Changed to new cables - still the left channel is distorted. Connected to speaker B terminals instead of A - still the left channel is distorted. I tried the headphones and initially thought that they had a problem too but here's the strange thing. If I leave the speaker selector where it is (i.e. speaker A) then I get the same problem through the headphones however if I put the speakers selector to off or speaker B they are crystal clear and perfect. So there must be something to do with the speakers itself causing inteference? The headphone socket is obviously the old type that just comes from the speaker output itself using resistors and it seems to be when selecting the speakers connected that I get the inteference. It only happens on the headphones if the speaker selector is pointed to the speakers connected. I have tried the speakers connected to A and B and both work fine with the headphones unless speakers are connected to them. I'm a bit stuck on this one. When I say the left channel takes longer to "build" volume I mean that if I turn the unit on the right channel will be at the volume selected within seconds of powering up. The left one can take 10 seconds and fades in. It is quieter than the right channel (about 2/3 of the right channel volume) and sounds like a radio signal with bad reception. The right one is crystal clear. I am only using the radio so nothing connected at the moment. I have tried it with the CD connected and the same left channel problem. Wondering if it is as simple as a transistor or capacitor. None of them appear to be bulging and there aren;t any leakages visible anywhere.
