    KR-6600: No sound in one channel after amp board repair

    I had some issues with transistor noise on one channel, which I fixed, but some similar issues appeared on the other channel. I decided to go ahead and replace everything on the amp board with a repair kit off of eBay; essentially everything but the resistors, in hopes of future proofing a bit...

    Kenwood KR9600 lost sound, but powers up

    Jamming nicely when sound just abruptly stopped. Lights were still on. Turned down volume, turned off, let sit a while and checked connections and such, cycled switches a bunch of times thinking possible loss of contact on anything. Turned back on and lights came on but still no sound. VU meters...

    Magnavox giving me the silent treatment

    I have been using a Magnavox 9303 tube amp fed by a Marantz 2230 preamp for the last 15 years. Love it. Suddenly there is no sound. I can even tap the bare input cables and there's no hum--it always hums slightly--and no touch response, nothing. At first I thought it was the fuse, but the tubes...

    Sansui 4000 Clean Up and Issues

    I acquired a Sansui 4000 (along with Sp-2000 speakers) recently. It wasn’t working at first, but I cleaned the pots and it started working. The tape monitor button was not holding, but this was not a big deal, I was mostly using the aux and occasionally the phono. However, I just acquired...

    Fisher cr-w862 Cassette plays but no sound

    So I have a Fisher CR-W862. Also I'm an idiot. Deck 1 and 2 played fine before I started messing with it. The only thing that was wrong was that the lamps were burnt out. There's a little board for the lamps, when one of the lamps burns out, then the other lamp burns out as well. I found...
