Revox Motor Capacitor Set for A77, B77, PR99. Very seldom are transistors a problem! However we do have a separate transistor and diode kit suitable for A77, B77, PR99 and other Revox and Studer machines for the 60’s and 70’s.
That's what I am being told by two techs but know that I have installed the Nagravox motor caps I am telling you my A77 has been taken to the next level! Just amazing. The best just got better!
