These are wideband FM receivers, companions to the RT-66,67,68. They are 
sensitive, rather stable, and not especially difficult to work on. The 
power supply is a plug in unit, allowing different input voltages. Most 
of the time, I have only had to re-form the large plug in electrolytic 
condensers, and check over the power supply. The vibrators may need 
servicing , as usual, and be sure to check the buffer condensers. They 
tend to get leaky after 60+ years.  They all had a schematic printed on 
fabric folded and stuffed into a slot. The tuning dial may have once 
glowed in the dark, treat it with care.   It's wise to always wash your 
hands after working on these older rigs, especially before taking 
refreshment. Great to use with the PRC- 6, 8,9,and10.
