    Giyas tipped up in the highs

    I assumed the owner has already tried (without success) to re-position the speakers. Changing the tweeter level is a very reasonable thing to try and is very effective. It is not making the speaker inaccurate at all. Many manufacturers (like Wilson Audio) have user-adjustable tweeter levels...

    Giyas tipped up in the highs

    I would reduce the volume of the tweeter by modifying the crossover. I have done this to many of my speakers and it's always an improvement. Many high-end speakers do have tweeter level controls.

    Sorry, I don't have a photo or diagram of the A80 motor interior.

    Studer a80 capstan motor service

    I just finished repairing a Studer A820 that the owner tried to repair himself. His effort were a complete disaster (he actually created more defects). And HE bought the A820 from from someone who tried and failed to fix the deck as well. So I was stuck fixing the original defects plus...

    Studer a80 capstan motor service

    That philosophy applies to the $10 old Sony RTR you find at a yard sale. However, it does not make sense to me to buy a non-working SOTA tape deck and just "sort of get it working" by fixing it yourself. What's the point of that unless you just want bragging rights? Remember that I have seen...

    Studer a80 capstan motor service

    Even if you did have a detailed picture of the motor internals that showed where every washer/shim went, it wouldn't help you. You would need to know exactly the dimensions of each washer/shim. Often those are not off the shelf parts, but custom sizes. A company that specializes in rebuilding...

    Studer a80 capstan motor service

    If you can't figure out what size washers/shims you need in the motor, you probably should not be trying to fix it yourself. Leave that kind of work to experts (see link). This deck is not some old Sony you found at a yard sale for $10. A SOTA tape deck deserves to be fixed right by...

    Treble, Treble, Treble... getting right is a challenge... Can Gear/ Systems Extend the Highs without Brightness? Why so Many Cut-off the Highs?

    Most speakers are designed to have a flat FR (frequency response) in an anechoic environment. When you put that same speaker in a normal room that has reflections, the treble region can often seem too hot. Back in the old days, most speakers had controls on the back for the tweeter so one...

    Troublesome 50Hz, 100Hz

    Acoustician, Dr.Floyd E.Toole states that as far as bass response goes, the worst listener position is at 1/4 of the room's length. That is where your couch is in your room diagram. Move your couch?

    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...

    Paul McGowan Prefers Digital

    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...

    Paul McGowan Prefers Digital

    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...
