    Studer and others Head shield

    Yikes! You were asking for trouble by putting that power amp so close to the tape deck to begin with. I would have moved the power amps, but if your solution works, then good for you. Does your Studer have a front head shield? (a flap that covers the face of the head)

    Studer and others Head shield

    A power transformer in a power amp will emit a rather strong electromagnetic field (EMF) that can travel several feet. If your tape deck is near that amp, the play head in a tape deck can pick up/detect that field which gets amplified by the play amplifiers, producing 60Hz tones (and harmonics...

    Maybe you don't want to pass on the mic feed. As in it needs to be filtered to some extent to be more listenable. I think this can be compared to film or video. When frame rates are increased from the old 24 fps, the technical accuracy increases, but test audiences almost always prefer the...

    Revox service recommendations

    Are you repairing the B77 ? If so, you can "re-emboss" the capstan surface yourself if the cost/time for bead-blasting is too high. Using double stick tape, adhere a strip of 120 grit sandpaper to the pinch roller and put the deck into play for 5 minutes. This will fix the common B77 defect of...

    As to obtaining "one of the best stereo sound experiences": Why not purchase the digital file, decode it with a "quality DAC" and send that signal though a black box that replicates " the typical analog processes of vinyl cutting and playback". That way, you don't have to buy: the LP, the...

    I agree, Tapeheads is a good place for RTR advice.

    Is slight turntable wobble normal?

    If the tone arm moves up and down, the wobble is vertical (not horizontal). -So does the record also move up and down? (you did not indicate) -Does the platter also move up and down? (you did not indicate)

    Is slight turntable wobble normal?

    Sometime a defective belt drive or suspension can induce a vertical oscillation of the platter.

    Has a client ever demanded that you crush a master? If so, how do you deal with that?

    Even one of the most vocal digital nay-sayers, Fremer, has had a gradual turnaround in recent years. Likely not that he has "changed his mind", but that digital is just getting better. He recently gave an "11" in SQ to a vinyl that was sourced from hi-rez digital. And the last several vinyl...

    Doesn't sound like you know what you are doing.

    Was the jack on the power amp or preamp? A bad jack would just kill the signal. It would not attenuate the highs (no tweeter output) as you claim. Perhaps the amp that drives the jack is bad. Did you try a full reset since this is an amplifier problem?

    No need to do a reset if the speakers were at fault. It does not sound like you tested all of the speakers. You need to do that. It is very easy and quick to do: You know the right channel output of you power amp works and sound fine. So hook up all of your speakers one by one to that same...

    So what was causing the tweeters to be dead? Was it the speaker or the amps causing that?

    Please help

    When you connected wires to your speakers, you could have inadvertently disconnect one of the two jumpers to the tweeters. Disconnect the two wires and make sure the two jumpers are connected and tight. Now install two banana plugs to your wires and plug those into the banana receptacles on the...
