    STUDER A80 Bearings and where to buy them - HELP!

    Yes, the bearings have a higher clearance but are pre-tensioned by spring washers when they are installed in the C37.That's why I find gringe friction more effective.

    Studer C37, rewind tape tension.

    Tension balance is undependent in winding mode, SB relay works as you say.

    Studer C37, rewind tape tension.

    I had time to check Voltage on the right Torque Motor. Stop - 67V DC measured to Ground Play - 55V (more break) to 65V (less break), depends on Tape tension Balance Winding forward - 62V Winding back - 52V The internal Meter, Position 5 - Bremsstrom stands at 1 during winding. Short Break after...

    Studer C37, rewind tape tension.

    You can see on the schematics, Laufwerk Schema, that the Transistor ASZ18 is regulating DC for Motors. It is controlled in winding with R14, Abgleich Bremszug beim Schnellwickeln. I think there is some DC also during winding (i will measure this in a few days) I just Could not feel it with my...

    Studer C37, rewind tape tension.

    Since the motors are not electrically braked when winding, the bearings of the motors and pulleys could be stiff. If these have never been exchanged, they should definitely be exchanged. I had installed Skf E2 bearings.

    I took SKF E2 Type. Very smooth, low friction and silent.
