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.
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 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.
For a time there has been a lack of good service facilities for the repair of tape decks but in time some of them have come out of the woodwork to make themselves know. This is a list of the ones I know do good work.
Not everyone is perfect and I even get complaints due to wait time. But on a whole these places 99% of the time will fix your unit well.

I am now at the point that I am taking orders for the gear that so many service shops and people need to fix their blinking transport lights problem. Teac does not have this part any more but I have had them made up. They are $30 plus the postage- I will not ship in a flat envelope like the $80 guy does on E bay. What does it look like-This is a Resin cast gear as were the original ones. Some call it gear B some Gear C. In the 122 Mk III parts diagram 4 the 4-34 part is what this is and was part number 5801474300 and sub’d to 9278377600.
To obtain one or some, contact me at email@example.com . I take credit cards- MC, Amex, Visa and Discover and can take Paypal as well. The cost of obtaining the gears has gone up slightly so they are $30 each now. Also know that the mechanism must be cleaned and greased prior to use or the same problem can occur. I have never had a new one fail yet. I use Lubriplate 105 to lubricate the mechanism first. Also the contact plate.
Every once in a while I get a guy who complains about the gear price. NO there are no $.33 gears nor $2.00 gears or you would not be contacting me. The gears cost the manufacture near $3000 to set up and make these custom made gears- he dictates the price he wants for them. There is conjecture that I make $20 profit on a gear and I can tell you that is not at all what they cost. There is a guy selling hundreds of gears on E bay who started at $80/gear. He sells them for $39 now. If you want to buy from him to save money then do so. There are a limited number of gears and when they run out that might be it. I use the same gears in repairs and there is no reason I HAVE to sell them. With enough of this aggravation I might not.
As of 1/27/2019 the postage has been increased to $7.90 for flat rate.
People have trouble buying good decks from E bay mostly because the equipment there is old and has had very little maintenance and some of it has been tampered with by amateurs. Well here is a place you can get a deck that has been checked out, calibrated and tested for correct function. They also have a 6 month warranty.
I will be offering Teac, Tascam, Nakamichi, Pioneer and other brands that have passed our testing procedure. There are units ready now I just have to get the pictures ready.
I have had units ready to sell but some of them sold before I could even take a picture of them to list here. It seems I can not get them ready fast enough.
Recently there was a repair that was done and the customer refused the unit so it is for sale here with a new capstan motor and belts plus all the alignment and calibration and a 6 month warranty. $185 The model is the DR-M14HX. Specs as measured can be sent to prospective buyers by E mail. Questions can be answered or further pictures sent as well.

People who have walkmans of the WM-D6C type continue to ask me if I have an AC adapter for it. Well I did a little research and came up with a limited number of these that can take in 100Vac to 240Vac and put out 6Vdc with a negative center post. These are made for these Walkmans and I have tested them with WM-D6C units. They are going for $12 each and have a 1 year warranty. It also comes with a smaller adapter that can work with other walkmans provided they are 6Vdc and negative center. 6Vdc at 1Amp.
These are switch type adpaters- Postage around $7.20 Priority mail.
I have been working on some machines that are clearly butchered by local shops. If I was to be doing this kind off work I would not put a big gold sticker on the back saying Electronic Sale and Service. The Service part is clearly not there. You have to be careful who you hand your equipment to and one of the first signs they are only after your money is the Deposit Fee.
Another thing I find annoying is that they don’t put all the screws back or that they put them in with a jack hammer and strip out the heads. Some machines that I get in show the only thing the guy who worked on it last was good at was putting a lot of wire ties on. Of course they all have to be cut out to correct his incompetent work. Just today I had a Audio board mounted wrong with tape and insulation foam added to the board. Why not save all this time and tape and put the board in the right way? They left the front pots not tightened down and then used a cassette deck belt in an open reel. It was real dirty inside but they did nothing about that. Maybe the dirt accumulated came from their shop where it sat for a long time. Of course it works well now. Teac’s lowest reel deck of the line an X-3 derivative called a 22-2 has a wow and flutter of .018% after I got done with it. Must be that AMS Signature oil I put in.
Recently I got a Pioneer RT909 in that had the belt changed in it and new Pinch Rollers put on. Yet the person at the shop completely skipped over the stuck Pinch Roller linkage and then when the 25 V zener diode shorted, he said he could not fix the deck. What kind of people operate shops like this- this one is in MO. I find it strange that they even take them in and charge for this kind of work- they are totally bogus I would say.
Some people have called and asked to get my address to drop off a unit or to ship them to me. Well here is that info-
