Default Re: Uher CR 210 Cassette Recorder Check Out

Removed the cassette carriage assembly. Now can see that the belts from the 2 flywheels to the 2 spool clutches are quite slack, also the main drive belt from motor pulley to the flywheels, so will get a set of new belts.

With main belt slipped off the motor pulley can see that motor pulley basically just oscillates (sometimes is just stationary) when unit is powered up and by touching the motor drive board can sometimes get the motor to spin at high speed. Looks like some sort of bad connection on the board maybe.

Cannot remember from my previous CR 240 work if the motor normally rotates/spins when unit is powered up (with no tape transport demand), if I could only find my 240 then I could check it out.

Since removing the cassette carriage, now have some control of the play and reverse pinch roller arms moving to the respective capstan shafts when Play or Reverse is selected. This control is intermittent and once again looks like bad connection/contact somewhere.
