Slow tape speed on reel to reel tape deck

The tape runs approximately 10 % slow. Their is no mechanical issue with slipping or jamming on any other such issue that would slow doanw the motor. Can the reason be a faulty capacitor? The tape deck is a SONY TC 230 (1970 vintage tape deck).

My TC-230 has the same problems and it is mechanical. Actually, its real hard to say what your problem is, but it is most likely the pinch roller is to tight on the piece that is connected to the motor. This extra tension is from a spring inside the machine and, when in storage for a long time with the machine set to stop, extra pressure builds up on this spring. Try leaving it unplugged on fast forward/play overnight. that might help.

Is there an internal speed adjustment to fix tape speed selector that has no affect on tape speed. This is on Sony TC-440 reel to reel.


There is a cam with solidified grease on a lot of Sony Mechanisms. The deck need to be cleaned of the grease they used that solidifies and then a better grease such as Lubriplate 105 should be applied.
The Idlers need to be reconditioned as well. The Sony units can be labor intensive due to this required work but I do fix them when people want them done. I am in the Chicago area as Skywave Tape Deck Repair

Why does tape go slow, then stops?


Gary hi! I am not sure whether your machine is solenoid controlled but if it is then I would suspect the solenoid that operate the capstan roller to be overheating, I had the very same problem with my Studer and Revoxes and when I smeared some heat sink compound (Available from electronic stores selling components like Radio Shack etc.) and fit if the chassis is cast aluminium like the better manufacturers use,as a heat sink. You can chech the belts and the lubrication of the drive system but I doubt that. Clean the capstan roller with denatured alcohol or cleaning alcohol.

Why is my tape deck running slow


Hi there! There are five general causes for cassette tape machines to run slow 1) motor faulty Check the motor governor electronics 2) Belts and rubbers worn or slipping 3) Lubrication of mechanism bushes 4) Cassettes binding in their cases this is quite common 5) If there is a solenoid or motor that do the work of the moving of capstan roller then there can be something wrong with that it can be binding on the sliding mechanism

Sony Tape Deck TC-630 D runs but the mechanisms that pulls the tape up to the heads doesn't move up when the control is turned to Forward. It moves just slightly, then stops like it's mechanically...


Commonly to all these older units and I have seen a lot of them, there are mechanical linkages that are not covered inn the owners manual as they were moving in the short term. Now after a lot of years the grease has turned to a glue or will be very thick. The mechanical links must be taken apart and regreased- I have done many but the problem is that it can take a lot of time to do this. Get a tube of Lubriplate from a Hardware store and go in and see where things do not move and that will be where the cleaning and grease will once put in make the deck like new.

I have a teac 3340 reel to reel recorder and believe it can only function in 2 speeds 7 1/2 ips and 15 ips. I have many reel to reel recordings that are 3 3/4 ips. Is there an adapter or gadget I can use...


In short, no. if you look closely you will see the Teac 3340 has a much larger/thicker capstan shaft than other Teac reel decks. This feature allows the faster tape speeds...7 1/2 and 15 ips. In order to slow down the Teac 3340 you would have to change the flywheel to one from another deck that was made to run at 3 3/4 and 7 1/2. Which is possible but some work..plus you would have to find a slower speed flywheel from another Teac deck. Also to maintain performance, the bias and Eq positions for the slower speeds would have to be readjusted from 7 1/2 and 15.

Tape Transport issue


FF and Rewind are functions of the reels, not the capstans. If the reels fail to rotate in response to capstan-driven tape motion the unit will assume a broken tape or end of tape. I think you have a mechanical reel drive system failure. Take it to a shop for evaluation and correction.

Tape will not turn


The more detailed the description of the problem, the better for diagnosing the root cause. Thanks.

It sounds like you have a couple of problems. I'll address them as you have them numbered above.

1. Decks typically have belts to drive the various 'reel' mechanisms. Therefore, they can slip without breaking anything inside the machine or the tape. Your first symptom leads me in that direction.

2. That it migrated is mysterious, unless Sony is using a common motor to handle both decks' reel duties.

3. This symptom may have something to do with the root cause of both sides jamming...

Do the cassette well doors come off, say, for cleaning? Could they be dislodge? If so, they may have something to do with the jamming problems in # 1 and #2 as the doors play a part in positioning the cassette and holding it in place against the reel motor cogs. How do the doors operate with NO tape inserted?

Does it take excessive force to close the door only WITH a tape? make sure the tape is fully seated before closing the door. The capstans (directly below each reel cog) have to engage through the small holes at the lower edge of the cassette. They should be straight and clean. Any dirt or oxide on them will cause problems as these are what move the tape at the precise speed necessary for good playback or recording.
---

My hipshot recommendation, otherwise, is to look around inside the cassette wells very carefully for any foreign matter, debris, dust bunnies.

Do you maintain the deck as recommended?

Motor plays at a very slow speed


capstan belt may be failing. check this by removing lid and touch the capstan flywheel when running. if it is easily stalled/slow to come up to speed and or the belt slipping badly then belt will require replacement.
