Rauland schematic
 

I am volunteering to work on an intercom system for a school. It's a
Rauland. The amplifier section is flakey...weak and intermittent
sound when sending audio from office to the rooms. OK when listening
to rooms.

The amp is model MCI350. The switching module is SCI 250 I think.
Any schemos out there? Thanks.
