    Distortion when playing lps, Shure V15 III plus Jico HE

    Hi all, I have a problem with distortion playing lps. Turntable is a Dual cs5000 with a vintage Shure V15 iii cart, Jico HE stylus. I tried the amplifier with another turntable and there was no problem, so it's not the phono stage. The distortion almost sounds like there's a glob of dust on the...

    Puzzler - why is turntable output suddenly lower?

    I have a strange situation with my Denon DP-47F. A few days ago, the sound got dodgy, like there was dust on the stylus. One channel went off intermittently. The stylus of the Ortofon 2m Red was clean. Eventually both channels played fine. But yesterday I replaced the cartridge with an Empire...

    My Mysterious 8-Track Deck Has Auto Stop Issues... Maybe

    A little while back, I picked up an 8-track deck from a thrift store. It's a Probe(?) DX-5000. I can't find any information on the company that made it, let alone any manuals. This is what it looks like: It plays and records fine, and both sound pretty decent for 8-track standards. However, it...

    Denon DRR-M10 Recording Quality Troubles

    For awhile now, I've had a Denon DRR-M10 as a secondary cassette deck. Playback quality sounds fine, but recording quality is not as good as I think it should be. So, I set up an experiment. I took 3 blank tapes: one I thought was a good example of a type I tape (a NOS Sony tape), one I thought...
