SOURCE: Repairing or replacing old tape decks

Hi m522posner

There is a surprising interest in "vintage" hifi products these days. Your tape machines probably needs new belts. Check this site out. You can get spares for your tape machine here. Belt kits are $17. He does repairs also, but the transport to and from may be an issue for you. I suggest emailing Bob, he may be able to refer you to someone in CA > I could do the repairs,but I am in Australia. :)

You could have a go at freshening up the belts yourself:)

SOURCE: play back on Sanyo mr-929 reel-to-reel tape recorder is backwards

I also have an MR-929. The information that you need is in the 'Stereophonic 4 track stereo''. As stereo is only two tracks, there is another 2 tracks in addition to the one you are listening to. Wind the entire reel to the empty spool, and then play that. As you have to physically turn the reel over to do so, you should then hear the other tracks (or track, if recorded in mono).
I use my 929 to play my parents recording of my family from the late 60s, which were recorded on a valve (tube) Ferguson machine, which had a green "magic eye" level indicator, which as a child I found fascinating!

SOURCE: My AKAI GX 636 records but can't hear anything on playback

Trace the wires from the head to the amp section. Put your finger on where they join (during playback) and see if you can get a buzz. If you can't on either channel, look for something that might be common to both channels. Either a switch, or a pre-amp IC, as being the cause of the fault.

SOURCE: I have a TEAC 3340 reel to reel recorder and

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.

Teac A 6010 reel to reel while recording my voice it echos my voice


You may be listening off tape and there is a lag of time between the record head and the play head which is what you may be concerned with. This is normal for any three head deck be it cassette or open reel.
Slowing the speed will lengthen the time of the delay and speeding it up will shorten it.

In order to maintain tape control and tension the reels always pull lightly in opposite directions during PLAY mode. The capstan moves the tape in the desired direction at a precise speed. If the capstan doesn't engage the tape BETWEEN itself and the pinch roller you'll get the reels battling over control of the tape. Check the tape routing.

The unit is eating up the tape!


Generally speaking, there are two reasons this happens.

[1] tape recorders have to move tape past the record/playback heads at a highly consistent and accurate rate of speed. What makes this possible is a rubber "pinch" or pressure roller and a spinning metal spindle. Tape is routed between the roller and the spindle, and when the recorder is in RECORD or PLAY mode, the roller presses the tape against the spinning spindle, causing the tape to move from the feed reel to the takeup reel. When the pinch roller and/or the spindle become coated with oxide particles shed from old tapes, they get sticky and the thin tape will begin wrapping around one or the other. THE SOLUTION is to get some cotton swabs and rubbing alcohol and clean the oxide (brown from cheap tapes and dark gray from better tapes) from both of these parts.

[2] many tape recorders use rubber belts and pulleys to turn the feed reel and the takeup reel. If the tiny rubber belt that makes the take-up reel turn is stretched, it will not wind moving tape fast enough, which causes tape to bunch up. If this is the problem (you will not be able to see the belts without removing the recorder's outer case), then you might as well junk the recorder.

If you see that the part of the rubber drive roller that contacts the moving tape has a ring of brown or gray coating on it, you

Incorrect record speed


do you have a reel to reel deck or another machine? You may also need a schematic. Make a copy of about 2 minutes of a tape on a working machine. Keep the original in the working machine. Each cassette deck needs a different size belt. Try putting different size rubber bands on it. Cassettes usually play at 1 7/8 IPS (inches per second) each speed increases or decreases by doubling or dividing by 2.
