    HELP WITH MOTORBOATING IN SYNTH CIRCUIT... Crumar Orchestrator.

    I finally got this thing going last night... tons of work and it's a complicated little beast!! But while I had this circuit working for a short time, I swapped out a transistor and now I have some SLOW motorboating going on... that gets faster if I adjust certain parameters. I'm realizing there...

    Jadis JP80MC info needed

    Hello friends. So I made my Defy 7 work, and it sounds great. But now my vintage JP80MC has developed noise in the left channel only of its MC stage. It’s “motor-boating”, which to me indicates either a bad capacitor, or a bad regulator. On my unit regulator markings are sanded off. On later...

    Pioneer SX-880 repair cost

    I have a Pioneer SX-880 that I bought a couple of years ago on Craigslist for $150. Has always worked perfectly except there has been some motorboating developing recently on all the inputs.

    Scott amp 299-D motorboating

    I have a Scott 299-D that has a serious oscillation or motorboating issue, (almost like a low frequency feedback) when it's in phono position with the loudness at around 2-3 o'clock with or without a tuntable. I can see the amplifier have seen some restoration : a lot of coupling capacitor and...
