    Revox B77 Record switch repair

    Go figure.. He is on the forum, reached out to me that way.. I guess as long as you did not lose anything apart from a little time then it's not that bad.. Why the scammer impression Charles, what happened in that regard??

    (One of) the most useless pieces of kit he has ever bought (says the purchaser)

    A few years back I employed a designer who came to her first day of work brandishing an entire collection of crystals.. She distributed them amongst the office area and even handed me one, “It’s to lower the negative tones”, she told me.. She lasted around 25 days before leaving in a fit of...

    SONY Cassette deck Repair/Maintenance

    Sounds to me that all that might be needed is a bit of contact cleaner in the pots, as it seems that no one has replied then you are welcome to bring the unit to me for a quick spray, maybe it works, maybe not, all it will cost you is the trip to Edenvale.. If it needs more, like belts and...

    SONY TC788-4

    Well, thats great news, well done, so often half century old grease is to blame for most mechanical problems on these machines.. Good luck with your search for tapes, I’m sure you will find from this forum, do yourself a favour and look up SSS or Sticky Shed Syndrome before you commit to...

    Tandberg TCD 300 Tape

    Hi Leon When you say no torque are you meaning the tape takeup reel not pulling the tape in correctly, or is it the actual capstan not pulling the tape correctly. the TCD300 is a 3 motor unit, did you go through the procedure of cleaning the capstans correctly, do they rotate freely with the...

    How often does an amp need servicing?

    Thank you Marantz123. This is the power supply section on that amp. The caps in the red block are the 6800uf 100V units linked into the +90 & -90V rails. You can see they are in parallel giving 13600uf. Given the parallel situation, best would be to remove and test each, and further to that, if...

    How often does an amp need servicing?

    I must note that I have a very similar amp in my stable which goes unused, and we did run it on Saturday to compare 'hum' levels and admittedly mine was somewhat quieter, the main negative on my unit is that horrendous torroidal transformer which buzzes like a bumblebee no matter how and where...

    How often does an amp need servicing?

    Unfortunately my Saturday ran away from me, but if you want to repeat the exercise you can come back and the first thing we do is gut the unit and remove the caps to measure their values, just maybe something comes back a little negative, but yes, that is the only practical way to see if a: the...

    Revox Motor Capacitors

    I have replaced the motor caps on my B77’s with as close as I can get off the shelf motor caps, the white plastic ones with a bolt and nut on one end and twin spade connectors on the other end. So if the closest I find is a 3uf instead of 3.3uf (as example, I cannot remember the actual...

    How often does an amp need servicing?

    Kinos you are jhb based, if you want to bring this amp past me we can quickly evaluate at no cost if the caps are originals or not, or if there has been extensive work done on this unit in the past.. The power supply is linear, its not a SMPS unit, so easier to work on for the tech needing to...

    Alignment Tape?

    Just remember to get the reference fluxivity spec from the machine you want to use as the source of the alignment tape and take that into consideration when setting your machines or you will be out by miles, it’s not all about frequency and phase once you go past azimuth and capstan tape speed...

    FdlSys - Sad news

    Some years ago I posted on this forum asking if anyone had any reel to reels gathering dust on an arbitrary shelf in a storeroom or garage somewhere, I was bored and was looking for adventure and stimulation stemming from the days of old…. There were replies, including Mikes where his first...
