    SX1050 No Power

    Hi all, please forgive me if this is a topic widely discussed somewhere I can't find, but I've been doing a recap and restore of an SX1050 and all was good until I replaced the power transistors with the wrong thermal paste (it was conducive and messy).

    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...

    Kenwood KR4010 I killed it and need help

    A friend asked me to service his Kenwood KR4010. It played but was real noisy so I knew it needed the usual De-Oxit treatment. I recapped the Power Supply section and had it sounding pretty good with one small problem. Sometimes the left channel sounded like a broken speaker. A little freeze...
