    Tuner locking off frequency - Technics ST-X302L

    Hi all, recently got myself a full Technics stack from the early 90's, and all is great with it apart from some annoying quirks with the tuner. I've got it connected to a good aerial in my attic, but it's getting quite weak reception on stations that it should be receiving well. I can make them...

    Automatic turntable doesn't drop needle

    My Sony PS-LX30 doesn't lower the tonearm when I try to play records. If I turn it off and back on again then it starts working like normal. Sometimes that takes a few tries. It also stops working when I leave it on for a bit without using it. Does anyone know what could be causing this?
