There are sites that are now offering MRL and Teac tapes that use their name but in reality they are duplicating their own signals on tape from who knows what kind of machines. This is one example-https://www.ebay.com/itm/BRAND-NEW-1-4-7-5-in-s-MRL-Four-Frequency-Calibration-Tape/392363532341?hash=item5b5ab06035:g:XaEAAOSwUPxdQc2f
These are fake and also not accurate and basically they are rip off artist that use reputable names to sell their garbage. Since when does Teac operate an alignment tape facility in Germany? It is all junk waiting to steal your money. Get MRL tape from good dealers like JRF Magnetics or MRL themselves and don’t buy the 4 tone cheaped out tape as this will not be as good as the real thing. I have been using MRL tapes from the late 80’s.
I know I can be negative at times but when I find a supplier that goes beyond the call of duty I mention that too.
That is Stereomanuals.com
Well the deed has been done. If you need a Tascam 58OB manual contact Rick at Stereomanuals.com as I just got my two copies and they are outstanding in quality and clarity.
Every page straight and without marks you get from other places plus you can read all the boards and schematics.
This is the only place to get correct and well made manuals. http://www.stereomanuals.com/man/rep/tascam/index.htm
I am in communication with certain people who are often E bay sellers and sellers of Reel Decks on other sites. One guy told me that 99% of reel to reel users do not know the machine they are buying is bad and so that gives him the go ahead to not adjust them correctly. Another guy who I asked what do you check the speed with as in test tape and measuring device? He answered it sounds good to me!
People are buying decks at higher prices and getting equipment with the most minimum of service done to them as well as them being off speed and who knows what they calibrate them to. All these people would be classified as Hacks by the good Technicians that exist out there. These are the Knuckleheads that you are being ripped off by as the decks are not even close to correct. I am writing this to make you aware of this prevailing mindset in the used equipment sales of Reel to Reel and Cassette decks. I never knew it was this bad and I do not intend to overlook the stuff I see. You can also tell how well the machine is worked on by asking what length warranty they have if any.
For those who own this machine there is a weak part in it called S301 which is the solenoid ALPs direction switch. Once this starts to go bad you can try and spray it with Deoxit but that might not even work given the tiny and poorly made switch design. The correct answer is to put a properly designed switch in by Kurt Jacobs which is sold on E bay. This fellow has done some homework and has made a correctly made part that should have been put in the deck of this price in the first place. Ebay Item# 153025190388
I, as a past Teac Lead Technician recommend this part!
If you watch this and think you need to pay $120 for this board, it is just another example of a person ready to rip you off when none of that is needed. If the left (Supply) reel table turns when you are suppose to be playing a tape in the forward direction on a Tascam 122 Mk III or 112 MkII, but this reel has drive to the left, it is because through handling the deck you have sent a signal to the controller that said to go to reverse mode. The deck uses the same IC as is in the 112R Mk II so there is a reverse mode in it.
How to fix it without $120 of fancy circuits that are not needed? A dB25 connector and a tact switch or even a set of wires that you can short together. Me in the business built a dB25 with tact switch- you only use it to get the deck in the right mode again and then disconnect it and you won’t need it again. What he is doing with all those ICs I have no idea. With the dB25 which fit the remote connector on the rear of the deck is connect pin 24- Ground to Pin 1- Play mode. The deck goes into play with this one push the correct direction. Now disconnect the remote connector and the deck will work correctly after that- I know as I have done it. I service these all the time. dB25 are pretty cheap and most Technicians and Broadcast Engineers have them sitting around like I did. Don’t be tricked into $120 rip off.
Recently I have been working on some decks here that have been badly butchered by local shops or so called Tecnicians that should really be called idiots because of what they do to these machines-
What has been observed are things like-
Broken off screws due to a drill being used to screw them in, stripped screws, Push on Pinch Roller rubber when they should be going to Terry for new rubber put on correctly. Cut wires all over the place, wrong belt sizes put on, power supply work that looked like a grade school person did it and I can go on and on. These people do more damage than good and then charge you for it. One service guy said to the client that he could not repair the deck- what was wrong with the deck? A shorted Zener Diode. How hard can that be to detect? A first year Electronic college student would be able to find this.
If you have a nice deck like this be careful where you have it serviced as a typical $300 repair can easily get into the $800 range when we have to take off motor plate stand offs and install new ones and repair all kinds of other destruction caused by the service person.
To add to this- I have just spent some time on the phone with a client who has had his unit repaired and recapped by this guy on E bay for $750. Now as he sends the unit back for the 4th time it still is not working. The client tells me he has a 3 year warranty. Talking about sticking your neck out far, I though I was doing that with 6 month warranty. Regardless of stated warranties and this is the second 3 year warranty I have heard of, these shops need to be able to fix the unit right the first time not the 4th or 5th time. In both cases of these places having 3 year warranties, I have had their clients tell me they had to send it back 4 to 5 times and in the previous case after 5 times the client gave up. I don’t blame him. Do you? If you ask me if they can not fix a unit after two attempts that tells me they can not fix it in the first place. Just be warned.
Anyone advertising on E bay for work can not be very good and this is the second proof I have found besides that guy in NM.
I continue to get calls that people want me to work on their dual well cassette decks. These usually sold for around $150. Doesn’t that tell you how they are made?
Suffice it to say that these decks of questionable quality in the first place run about $400 to repair as there are two separate transports to tear down and rebuild. Is is worth it? Certainly NOT! They were considered throw away when they were made many years ago. The target audience was the 16 year old high school girl- does that tell you anything about the quality and their purpose?
If you have a broken one of any brand that is dual cassette, you are far better off getting an older solid made single deck like a Teac C-3RX or a Tascam 122 Mk II. Nakamichi BX300 is also another good product. You can’t buy a piece of junk and expect the Technician to make a piece of gold out of it- I have worked on them enough years that I know this is not going to happen.
Out of all the dual cassette decks made there was only one worthy one made and it was a Sony ES model that cost over $1000. That might be fixed.
For those that are not informed and have no way to measure wow and flutter as well as phase shift with a scope, I am posting this so that you DO NOT waste your money on this garbage.
I finally tested a set here and had to wonder what was the problem with the freshly oiled and belted deck and it was the Pinch Rollers. These Pinch roller push ons are a bad attempt to make a product but if they did any testing they would find that they exhibit cyclic wow and flutter rising to .14% and that they are not very precise in that the azimuth sine wave shifts consistently at least 90 degrees each way. This is ridiculous that these are still being sold. I looked on Amazon and there are two 5 star rating reviews.
In putting on another pair of old rollers I had here the wow and flutter went down to .040% wrms and stayed there.
This is another rip off product to be sold to those that do not know better- my results have been confirmed by two other Technicians.
Also be aware that this same idea is being sold for Tascam cassette decks and the more expensive Open reels. No matter what the product is, the push on rubber is crap and you will NOT get good service from it. The only way to fix a Pinch Roller is to send it to Terry Witt in Sparta Michigan. This is what the professionals do. Don’t let these numbskull’s take advantage of you!
Each billing cycle I have to go around in circles wasting a lot of time to get Dish to get to the amounts of billing their last agent promised. They make promises and then do not follow them. Direct TV is no better and probably worse now that incompetent AT&T owns them. I have good stories about them too.
I suggest you get a Roku box and Netflix and do away with all the Morons and idiots not to mention liars at DISH Network. They charge you all this money and still have commercials in the programming- that is all crap. You can get that from free by watching METV.
Comment with your experience. I wish Satellite would go away.
For those of you with expensive portable equipment or even flashlight like Mag-lites. One of the worse things you can put into a device is an Alkaline battery. They are destructive and leak every time. They could be considered hazardous material the way they destroy electronics by their leaking and corrosive fluids. I am surprised that the EPA has not outlawed these terrible junk batteries and there are many better choices that will cost you less in the long run. I suggest you get Tenergy NMH or Nickel Metal Hydride batteries that may cost more initially but when you can use them 1000 times there is not a lot to figure out that they are worth a pile of money saved. I even have some AA cells from 2001 that still work. The important part though is that the DO NOT LEAK. Abandon the purchase of junk Alkaline batteries, save money and your equipment too. Head over to All-battery and buy the Tenergy product like I do and no more trouble. No I do not own or work at ALL-battery. I just have had very good luck buying their product and not one failure yet- 9V all the way to AAA and they have rechargeable 123A batteries too. Here is to make it easy for you-
It is a very good chance that this deck will become a part unit with that kind of damage.
