I have a Revox PR99 that I am trying to calibrate. The deck was completely recapped and transistors replaced also. I am following the manual to the calibration and I am on the step to adjust the Reproduce Level output. The deck can record and playback. But the playback is very low. I can also hear the 1khz tone from the test tape through my headphone.
So: What I am trying to do is to adjust the Repro Level according to the service manual and I am supposed to turn the Repro Trimmers until I get the operating level +4dB (1.23v) and I should see that reading on the millivoltmeter also. Neither the millivoltmeter or the VU meter move when I turn the trimmers. The VU meters are working: when I am in the record mode and record some music, the VU meters work. But on playback they barely move. I think I will have a look at the Repo Amp PCB. Any idea what could be going on?
