Tape Deck Repair Questions I Get

I am often asked what book do I read to tell me how to take this mechanism apart in order to fix it like a Technician?

The answer is there is no such book. Decks of different models are built in different ways and if you are an expert in Teac decks this does not make you an expert in Pioneer decks or Otari. They are all designed with a like need and function but using different parts and structures.

So a person asked me how to take a X1000R pinch roller linkage apart. I basically told him the basic steps. It does not mean that every detail is included in that small list of instructions. Where does all the detail come from then? It is a thing called experience. Experience and know-how is developed over time on a bench when you work on 20-50 decks of different types. Once you work on 100 to 200 you will have a higher confidence level than a beginner as you know something about the subject but not all. Then there is reliance on other Technicians. If I after 45 years come across a deck I have never worked on like a Revox or Technics, I contact one of the guys that work on them all the time. Leon or Marc will then tell me what they know and maybe some things they have come across that I might encounter. People contact me all the time about Teac and Tascam decks and I help them. To become proficient in tape deck repair as I tell people I am training or helping to start out, is that you take in everything you can and use those to sharpen your mind as to what you will need to repair decks. The issue is that if you take in some real junk then you will work through all the problems which could take a long time but when done you will have gone through the first course of deck repair and will have accomplished something. Even if the deck has Idlers and goofy design if you are able to make it work at least somewhat well you will have overcome many obstacles in that mechanism and then when you work on a better and more properly designed product then you will appreciate how well some things are made. At a later time you can define what you want to work on and then get away from junk like Akai decks that have no heads possible for replacements. This is why I don’t take them in anymore.

There is no magic wand to fix these- or what the magic wand actually is- is hard work and applying yourself to the task at hand and learn what you need to know as you make your journey from startup to seasoned Technician. No one starts out at the Admiral level you need to start out at seaman level first and make your way up the ladder to higher levels- ask questions and use logic in your decision as well as some common sense. Do NOT think that changing boards is the magic answer as most the time it results in further problems to solve rather than an easy fix. If you have questions I can answer some here.

Teac X1000R Speed Mods

For a time now I have been fighting with some units speed wise where the forward direction is set a 3004Hz and then the reverse direction come in at 3035Hz. Well there is only one adjustment and it is wrong to place the forward speed at less than 3000Hz due to the human ear hears slower better than a faster speed. So I said one day a guy will figure out a mod to fix this- why does it always end up being me?

Well now a mod is designed that takes a signal off the reversing solenoid ground path to switch a relay so that when reverse mode is had the speed is adjustable to exact values by a 10 turn trimmers. In doing this you also need to provide the forward trimmers which are also improved from the single turn pots they used on the servo card. Now for both directions and speeds we have exact speed setting so that Musicians with perfect pitch do not have to suffer due to this design error.
