    No Sound on Panasonic RQ-2103 Tape Recorder

    Some time back I acquired a Panasonic RQ-2103 tape recorder from an estate sale. When I was first playing around with it, it seemed to work fine until I somehow blew it up. What's strange is that there's no burn marks or anything that I can see. It looks clean. Despite this, upon revisiting it...

    Problems with Pioneer CT-540

    I recently acquired a Pioneer CT-540 cassette deck, and it has a few problems. When in the play mode, the reel on the right won't move. It also won't rewind or fast forward.

    Speakers connected to JVC AX-R97 get quiet when you turn on Rear (aka B or Remote Set)

    Long story short(ish), as soon as you turn on the secondary set of speakers on my JVC reciever, the primary speakers lose almost all mids and treble (sound muddy). I discovered this issue when attempting to add a sub with an integrated amp, but if you press the button to turn on the secondary...
