Hi,

Right now I play my 4-track pre-recorded tapes on a Revox A77 which seems to be the MK-IV version as per silver push-buttons.
I recaped almost all except the motor capacitors and two 1600µF electrolytics on the playback amplifiers (I'll change them soon anyway).
I would like to get the best sound I can from this machine, without expecting more than it can give.
As I'm using this machine in playback more only (I record on a 2-track PR99 MKIII), I removed all the plugin boards except the two playback amplifiers.
What I wanted to know is whether there are any known changes (excluding head changes) which would improve the sound quality.


Thanks,

David
 
It's most likely running at a maximum speed of 7,5 inches per second. Modifying it to run at double speed would improve the treble response and make it less prone do dropoffs.
 
I don't think that will help with prerecorded stereo tapes, the commercial ones were either 3.75, or occasionally 7.5.
 
Oops, you're right JP. Didn't catch the word "prerecorded". Sometimes I need to think before postning :facepalm:
