Hi guys and gals. I really need your help. I bought a revox a77 and when listening to it I hear 2 recordings? On play back. So I recorded some new music and again I hear 2 different songs? It also sounds a little distorted in sound quality. I cleaned the heads ect. But on stereo play back I hear 2 different recordings. Please any help would be appreciated. Thank you very much.

Seems that head alignment is way off. You need to find test tapes for tuning RTR machines and go through the full mechanical alignment procedure. In that old unint you will need to do electrical alignment too. Unless you have experience and tools, you will need to hire someone to do it for you. This may cost you several hundred to do it right.

Does it, by any chance, have half-track (instead of quarter-track) heads? If it did, though, the "other program" channel you'd hear should be backwards.

My A77 started life as a regular ol' quarter-track machine, but I had it modified to the half-track, high speed (15/7.5 ips) configuration when it was rehab'bed years back.
Consequently, it can not play normal quarter-track stereo (two sided) tapes any more.

So -- while in some respects a cheap ReVox is sort of like a cheap Mercedes Benz (some folks say, "the most expensive car you'll ever own is a cheap Mercedes Benz), the A77 is a classic and, if the deck's in generally good shape, you may want to invest in professional restoration. It won't be inexpensive, but the end result can be a deck that is (still) capable of world-class performance. Any "original condition" ReVox will need work; they're chockablock with capacitors that need to be replaced at this late date.

Here are the parts donors that gave all to help the one in the photo above rise from the ashes :)

My first thought was you were trying to play back a 1/4 trk tape with a two track machine. But then you say you get the same effect when you record a tape to. If you use virgin or bulk erased tape doyou still get the same effect????
