1973 NuTone 2561 Avocado Master Station Power Supply

The design of the 2561 improved and were simplified over the 17 years it was in production, and the power supply was no exception.  Gone are the 2 large Orange Paper Capacitors that were always mounted behind the rectifier board.

Also gone are the secondary chassis transformers.

This new and simplified board has a single axial capacitor and a old school Sprague Multi-Section Can Capacitor.
