Is a RM-503 anything like a RM-561A? Someone gave me a 561A a number of
years ago, but it is still in need of a power switch. The switch is
integrated into the brightness control, and doesn't seem to be a standard
part.

One of the more unusual things I noticed about the Tektronix scopes of
this vintage is that nearly all the components are connected via solder
joints bonded to silver plated notches in ceramic strips. It sure beats
the tag strips often found in other bits of vintage electronics gear...
