[TMC] TMC R-5007A/FRR-502 Receiver

[Albert Santangelo]

Looking to find a Operating/Technical manual for this receiver. It has
RCAF tags on it. Works well, except that I can't get the BFO to function
at all.
The receiver is similar to the FRR-49, but there are substantial
differences in the tube line up in the receiver itself, and the plug in
modules.
I've seen the manual currently on E-bay, but its a manual for the
FRR-49.
Can anyone offer any assistance.
Thanks,
