Teac Reel Table Adjustment
I adjusted Reel Tables on 7 teacs last year. This may save you some time and avoid trouble adjusting Teac Reel Tables.
My collection of TEACs come in 3 varieties:
a. Old Style, Real Wood Side Panels or Plastic Laminate Side Panels, Silver Fronts
b. Medium Period Style: Plastic Face Plate, greige color (grey/beige), either darker plastic rear case, or same but covered in 4 Sided Wood Look box
c. Modern Style: Thick Aluminum Face Plates, Silver or Anodized Black, either darker plastic rear case, or same but covered in 4 Sided Wood Veneer Box
Cautions:
a. Verify that all your tension rollers and tape guides are working properly first: free movement, but, not too loose that the tape can move in and out slightly when running.
b. It is easy to damage the wood boxes, or scuff up your plastic case, so, be carefull during this step, protecting rear edges as well as the 4 sides.
c. Once the cases are off, it is easy to damage the edges of the face plates, so, continue to be careful. All the work, fixing things and then some damage is a shame.
d. The interior end of the left reel of early style machines has a notch for the counter belt. To avoid more work, try to keep it in the groove while working. Good time to check it to make sure counter belt not too loose or too dry and the two pulley notches not too dirty.
e. Occasionally a warped reel looks like poor alignment, so, do your set up with straight reels. Some rare old non-standard overall thickness reels exist, so verify yours are both 'normal'. If it is high up on the shaft, hard to tighten when you go to lock it on, thats the rare too thick one.
Do not remove the exterior Reel Table face plate, (black rubber, reel shaft, 3 screws), they need to be on for the adjustment.
Once Rear Case(s) off: a decently long shaft screw driver or long shaft allen wrench will be needed to reach and loosen the two screws that tighten the reel to the shaft. The screws do not need to be removed, just loosened enough to allow the reel to move in/out on the shaft, then tightened up again. Less chance of dropping and losing them.
Preliminary Adjustment: I found that all 3 styles aligned properly with the tape path when there was a clearance of 3/16" between the face plate and the rear face of the reel table. I found a sheet of rubber material 3/16" thick, I fit it between them with rotation just possible, and make a preliminary tightening of the interior two screws, and run a test, and bingo, typically right on, then tighten them up.
The tape should center itself within the interior space of the reel, avoiding rubbing either interior edge or stacking off center: both reels. Check at play speed and at ffwd and rew speeds. Watch it for a while as the tape gets onto the reel you are watching.
If even slightly off, take the time to make any minor adjustment as you do not want to damage the edges of your tapes, or have poor winding onto your reel during storage and next playback.
If you take the time to get the inside cover off, and you are handy enough to make this adjustment, well, this is the time to check, clean, oil, etc.
