Revox A 77 please help with input and output connections

[355F1]

Chaps,

I have just bought a reconditioned A 77 high speed deck from Germany and I want to be sure about connecting it to my preamp.

I think that Revox uses CH 1 and CH 2 instead of Right and Left channels. The owners manual is poorly written.

I think that I should connect the Microphone Inputs via Phono Sockets [28]
to my preamp Tape 1 Outputs and the Outputs via Phono Sockets [30] to the preamp Tape 1 Inputs.

Please see attachments.

Any help will be greatly appreciated.

Best regards,

The microphone inputs have very high sensitivity and should only be used with .... wait for it .... microphones!

You should be connecting to Tape In / Tape Out, AFAIR which is Aux Input and Output on the A77

You definitely want to use the AUX input not MIC input for recording line level sources.

IIRC CH1 is left and CH2 is right, but I got rid of my last ReVox a couple of years ago so recollection might be faulty.

Hi 355F1,
Yup, Kevin is right. You must use high level inputs for your tape loop in your equipment. Also, a weirdness the A-77 has. It reverses channel I and channel II from record to play. Don't ask me why, it just does.

I used to do do warranty on the Revox product. Excellent stuff. The B-77 does not reverse the channels from record to play. The A-77 does have a potential problem. It has many tantalum capacitors that go bad. One is on the capstan motor (PITA to replace) while most of the others are on the circuit cards. Do you know if it has any work done on it before it was sold to you? If these haven't been replaced yet, you should have them replaced before you begin doing anything serious.

Yes, the tantalum capacitors are prone to issues on this deck. I would also suggest replacing all electrolytics, as well, if they have not been gone through.
