Connections for a Grundig reel to reel tape recorder

I have an old Grundig tape recorder (1960's) which I wish to connect to an external tuner to transfer the recordings to my computer. It has Din plugs with symbols on them, but I don't remember what they stand for! Can you help? One symbol is a double wavy line, like '' = '', but wavy. Another symbol is a square with the right hand edge protruding beyond the edge top and bottom, like a square '' d '' without long upstroke. Another symbol is like a '' Q '' but reversed right to left. I hope you can help! Thanks very much. Bill Hart (Warrington, Cheshire).

With a bit of luck you may be able to find some adapters to allow a plug into the Line IN port of the computer.

Here is a site that appears to have the Grundig manual if you register ( its free). There may also be some very knowledgeable people there that you provide the info you need.

Hi my Dad has an Akai 1710 reel to reel tape recorder which is in good cosmetic & working order. However when the take-up reel has about 1/3 of tape on it the motor tends to slow down somewhat. What...

Most of the old tape units had rubber "pucks" and belts thaat drive the reels..

The pucks tend to dry out and deteriorate. You MIGHT be able to restore them a bit with the spray used to restore typewriter plattens.

I am about to begin recording reel-to-reel tapes to CD's. Should I be concerned about deteriation of tapes made in 1980

I have successfully dubbed tapes at least as old as this, probably older by a margin. If the tape plays, no problem. Just make sure that the machine heads are clean before you transfer each one.

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!

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. :)

Vintage Electronics
P.O. Box 941

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