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.
