Gary,
The manual for the R1011B bench power supply is 6881069A94, which is still
available for purchase from Motorola Parts for about $24. Call 800-422-4210
to order.
I saw a few used manuals

from, but they WILL give you the latest manual or part number to order.

In the building and testing phase of a system, two power supplies are
being used. One for the power amp and one for the repeater/exciter, fan,
controller, etc. It appears that a ground loop may be emerging as the
culprit in why some sort of oscillation or cycling of the repeater goes on,
I've exhausted the usual suspects (DigiKey, Mouser, Newark, etc.),
so I'm turning to the world-wide bank of experts here for advice.

The RM-50M has been around for many years (at least 20). It's the Rack
