After prodding around a bit I noticed the issue was with the potmeter which in hindsight makes a lot of sense as the knob was damaged already so it most likely had some sort...

    Audible interference on Sony CMT-EX1

    Acquired a CMT-EX1 a few weeks ago, but quickly realised there is audible interference from the speakers, in one channel more than the other. Have opened it up, and I’m getting interference right back to the outputs on the amp chip. However, the digital-sounding interference is **independent**...

    Hey, I've just had a Marantz 1060 recapped, obviously I expect a slight sound change when that's done, but I don't think I was ready for just how much bass I seem to have lost. An old hiss is now gone, and the mid and highs seem a lot clearer, but I've also lost the tight punch and low end...

    "Working" receiver does not put out any audio

    I have recently come into the possession of a Kyocera R-861 receiver. It was sold as "working". It looks like a very lovely machine. The wood-grain paneling could use a little love, but I will fill in the broken-up edges with wood putty and carefully paint it to match the veneer. Won't be...
