    Where can you find "How to do preventive Maintenance on a Pioneer 701-RT Reel to Reel?

    Well as I get older I seem to be getting more guys wanting to get into repair business which is good. I have a new trainee here local and then Terry's son who wants to get into repair and then a newer guy who contacted me from Madison WI. Tooling up and getting the right equipment might take...

    Tascam 122 Mk III Gear C available

    Well time has gone by and the last $1000 order is getting thin now. What makes it worse is I don't have the money to order another $1000 worth. One of my trainee that is local is tooling up his bench and we should get some result from this guy as he is gun ho for doing work- a lot of them are...

    HF loss - general

    Well I do know- First the Bias oscillator is powered by a DC supply and as this decays over years with a low grade or cheap electrolytics in the machine it also causes the voltage to go down on the supply of the Bias Oscillator thus a change in performance. This is why Dan and I and my trainees...

    Professional reconditioning of magnetic heads

    I am not in the relap everything camp in fact very much the opposite. Cassette heads have to be put on right at the start. If they are not then all the tapes you made on that deck are off and now you want to change the head? While the concept of a pad lifter might be good on paper, I don't think...

    Professional reconditioning of magnetic heads

    He can not make worn out heads new again which is what a lot of people think about lapping. Professional heads are the ones that best benfit from lapping if you want to do it.

    HF loss - general

    Heads should be examined with a eye loop or some kind of magnification. Still you need to know what wear looks like on different heads. On ferrite it looks like a white abrasion that should not be there. Glass heads might look a bit the same. I thought on the graph that record EQ or bias would...

    Cassette decks RF shielding

    Don't be so sure. Cell phones use very high frequency which propagates pretty well. The front of the deck is where interference will get in and that is usually covered by plastic or aluminum. It is best to get cell phones away from a tape decks while doing any critical recording as you might get...

    I have every confidence in Alex's ability and advice. He is almost the only one I listen to myself. But let us not make him Pope. I don't think he wants the job anyway.

    HF loss - general

    Regular good Technicians can mount a head- it just takes an understanding of what is needed. Many decks do not have the hardware to move heads in a lot of directions and mostly only the Nakamichi decks do. The Tascam 122 Mk II and Mk III were much better. People have worn out heads and think...

    Tascam releasing a new type-II cassette

    I am short on money now to buy these but it really is not my job to evaluate products from producers. It just makes me mad when certain companies try and pass off garbage tape like the BASF for Studio Master tape and it is clearly lacking and I can not adjust the 488 to it as the record pots do...

    The Tascam 42NB LIVES!!!!!

    The only strange part that I have had to get made is the tachometer roller because people bring them on totally missing. Why don't people just leave this alone and let the Technician deal with it as the making of a totally missing part cost way more than just getting the rubber put on present...

    Tascam releasing a new type-II cassette

    I was thinking about that but what if I don't like it? I would not want to cause them any harm. I do not say too much about Capture tape either for the same reason.

    Tascam releasing a new type-II cassette

    Hey I was on ATR shop site today just to check the cost of 1" tape and I saw them selling ATR cassette tapes that are $19 which are chrome C-60 with the reels in them. So it seems like these are popping up in a lot more places and Tascam is not the only one with them. It is too coincidental that...

    The Tascam 42NB LIVES!!!!!

    All the more solid made Tascam decks work great in my experience but the adjustments need to be done right. You only need to buy a Tentelometer one time and then you will have it from then on. Alignment tapes are not $39 either and they wear out. What parts do you have trouble getting? I know...

    Need help about understanding power transformer of a cassette deck, please.

    That would be wise as this would make things less complicated. They know what the deck consumes power wise as stated by serial tag so now it is just a matter of selecting a couple transformers to do the job- you can work on the high side of power as a transformer made for more amps will be...

    Need help about understanding power transformer of a cassette deck, please.

    Well it will be interesting on what the solution comes to be. A technician with all kinds of parts and test equipment around might be able to rig up a test system with several power supplies- they don't have to be all from one transformer. There are some rare cases where two transformer were put...

    Need help about understanding power transformer of a cassette deck, please.

    Transformers are usually not regulation devices and certainly not in these decks. To put in 220Vac and still get 12 V out is very unusual unless you have a transformer that is designed to do that but I suspect his measurements are wrong. Transformers are voltage conversion devices and also...

    Cheap cassettes at *Warmalt

    My comparison of tape is by type- Metal to Metal and so on. There is no need to compare Metal tapes to other as they are on entirely different settings. The decks are designed to give compatible levels from each tape but the Sony XR tapes are a new development different than the MA and those...
