    Jasmine LP-2.0MK II problem

    It seems that I have no lucky hand in buying second hand audio equipment. I recently bought a Jasmine LP 2.0 MKII phone preamp. As I understand this is a very good pre amp at a reasonable price. Unfortunately I’ve never come around in really testing it. After I received the amp, I hooked it up...

    Now to start this off, I don't even know if this is the right place to put this since my JVC isn't exactly "vintage". It's from 1993 and actually looks newer, so I honestly don't know. Second, I'm new here...as you can probably tell. Alright, now on to my problem. So a while ago my poor JVC was...

    RT-909 - pinch rollers engage when fast-forwarding/rewinding

    Hey folks, As part of a restoration project I'm working on an RT-909. When I press fwd/rewind, the pinch rollers engage, and thus it pushes the tape up against the heads. Very undesirable obviously! Now I've already rebuilt the tension rollers using Rich's guide (thanks!!), and they perform...

    Help: Sony amplifier F660 ESCD input feeds all inputs

    Swiching to "Tuner", for example, goes quiet for a second & the CD keeps playing. It worked until a month ago, no changes have been made. Should I just junk the 660? Sorry for typo: the Sony TA-F606ES is the amplifier - the CD input distributes across all the switched inputs.

    I've recently replaced the output transistors on one channel of a PL400 I'm working on but I now have a big DC offset. When I got the PL400, it arrived with no main fuse.
