Belles 150

 

 

The customer reports hums and noises from this amplifier.   Our bench test reveals problems with the Power filtering caps and input transistors.   The transistors were matched from a batch of over 300.

 

We also performed upgrades to the power supply, and changed the caps to Mundorf.

 

Total Cost of Repair: $ 300
