Uher 4000 : le magnetophone portatif des annees 60-70s

Trouble shooting

• Motor servo problem–UHER 4000 Report-S
  • t apparently was, was a Polysterene capacitor in the motor control circuit was shorting out, causing the regulation to fail, and the motor to run off full voltage… So I replaced the capacitor with an “orange drop” capacitor of the same value (0.0015uF if I remember correctly) and it works beautifully, no more motor speed problems ever since.
