The good part is that it makes these very expensive and desirable machines look totally broken, so you can get them for good money. The repair is extremely simple and cheap - just replace every electrolytic capacitor.
Electronically the ReVoxes are great to work on - NO use of exotic ICs that you can't get anymore (as with Japanese direct drives). The mechanical parts may be a bit harder to find - notably the cueing damper used on the *first* series of B790, but later upgraded to be immortal.

"Frako" brand capacitors used in all ReVox components from the 1970s and 1980s are now going short circuit. It is a very, very common 'fault'.The good part is that it makes these very expensive and desirable machines look totally broken, so you can get them for good money. The repair is extremely simple and cheap - just replace every electrolytic capacitor.
