I Need Some Help With A Revox A77
I'm hoping someone here can help me figure out a problem I'm having with my Revox A77.
It is a Revox A77 Mark III professional version half-track with 15 1/2 and 7 1/2 ips speed. It has been a great machine for many years. I haven't used very much lately but I wanted to fire it up and maybe play some of my old masters.
When I powered up everything seemed fine until I discovered that one of the channels was not reproducing playback. I tried it with phones and also the RCA outputs to the amp. It seems that channel 2 is shot at least in playback mode.:scratch2:
I pulled it apart and switched the playback cards (after cleaning them with contact cleaner) and the same problem exist. :sigh:
If the problem is not with the playback pcb, where should I look next?
Any ideas or help would be appreciated.
