Help with a Marantz 2220B receiver
#4

Yes. But there are no pots or regulation for the main voltage. It is rectified by H007 bridge, filtered by C006 4,700uF 63V cap and goes to output amp board P700.
Where have you seen any regulation?

The regulated 35V feeds P500, P300 and P900 but none are the output amp.

What you could do is disconnect one of them at a time and see if the voltage goes back to 35V or so, then you woud know who loads it.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
