Machine had fault were 50 V fuse kept blowing. I think that was loose reel turntable causing the Reel drive to crossbar the supply, whenever it got out of step. That sorted, but now unable to align the Audio.
Unable to get any change in adjustment parameters in Level, hf for Repro Sync and record. All speed, All eq.
BUT can control bias level.
It was storing tape position. ( Latest test, seem to indicate that no that is not happening, but unsure about the reliability of this test).
My fear is that it a faulty MCM2802. eeprom chip.

Does any one have Bin likes for Studer A807 mk 1, current version installed was 40/87, but can change to later version if available.

I have a Studer A807 and I need to replace the pinch roller because the old one just "melted" and thick sticky rubber ran down the front of the machine whilst it was in storage.

Can anyone explain this?

I haven't put chemicals on it and its just a mystery to me.

Thanks
