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.
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 to 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 sing 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 start 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.
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-
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 have been working on units a log time and some of the time I get requests for help that I do not have manuals for so over to Hi Fi Engine I went. Most of the time I was able to help the other guy for no cost. Well most recently I was working on a Sony 854-4 where I got the manual from Hi Fi Engine. The schematic is so bad that you can not see what the part numbers are- what idiot scans stuff like this and what further idiot puts in on a site for some poor person to download and try to work with.
Well I made a comment to them about the poor quality and now I am done with their poor scans and idiotic behavior. Why don’t they come up to standards rather then kick people out from downloading their garbage.
No matter, I am not going there anymore and do not suggest to anyone that you do either. If I can not fix a product with all my experience and their blurry manuals what makes you think that a person just starting is going to be able to.
Get all you manuals in paper from Stereomanuals.com
This place will get you a good and clear product. http://www.stereomanuals.com/index.htm
I keep on getting comments on how people want a blog like the one here that I put up. Well, it is not that hard to do and it is very affordable. This link here will get you to the trial one month evaluation. Actually for the quality of the product they deliver and at a terrific price it is a no-brainer.
I highly suggest that you look into this and not pay some SEO person hundreds of dollars to make you a different site. You found me didn’t you?
These items listed here are ready to be sold. Not every one will be a Mint as these are older units and often times rescued from adverse locations. Many of them are very acceptable and the pictures here are of the actual units. More units will come available as they are finished.
Pioneer CTF-700 $300.00 Shipping is extra. If interested or if you have questions, E mail firstname.lastname@example.org
This unit was sold and I have not been good as listing things here as there is no time for it but there are other units to sell. I have two NAD 6300 units to be sold too. A few open reels decks too.
A Teac A6300 is ready to go as I finished it and did a test recording tape on a whole XL I 35-90. Works perfect.
The owner wants $775 and it has a 6 month warranty. It is calibrated for LPR35 tape 50-20KHz at 0 Vu plus or minus 2 dB when using 7.5 IPS. At 3.75IPS the test recordings did not sound bad either. Comes with NAB adapters. You can also make an offer and I will relay it to Bob.
A Teac A4300SX is also available as soon as I get some pictures of it at a lesser price.
