Crown D75A issues

Recommended Posts

One channel in the D75A has dropped substantially in output, this is used for powering monitors in one of our edit suites, we isolated it to channel 1 in the D75A. Where can we find a service manual or schematic?

Ask me in PM for the schematics.

As a start, is the level control working well? Does the control attenuate the signal normally?

Did you get to swap the input IC100 (33079)? Did you verify signal at the output of U100A (Ch1)?

Did you pass sine? What was the shape of the signal at the output? Was it distorted or just very low?

How does the Ch1 react when non-loaded? Is the signal strong now? Is it still low or distorted?
