Marl Levinson No. 333 Dual Mono Amplifier

 

   

 

 

 

The Mark Levinson No. 333 Amplifier was brought in with a high level of hum and noise.  It failed our bench test, and our distortion test.

 

Several problems were revealed:

 

* Capacitors has leakage

* The component was shorted to the ground

* Coffee has been spilled into the amp.

 

We replaced the capacitor, fixed the hum, fixed the shorted areas of the circuit, and re-adjusted the bias.

 

The amp passed our subsequent bench test.
