Manufacturer: RCA (USA)
Model: 155, S#P811A
Vintage: 1939
Purpose: General Purpose
Condition: Not original, Working
Comments:
Oscilloscope in very nice condition for its age and compared to the other RCAs of that era. Some parts of the power supply circuit are not original, no surprise. Just to be safe, the capacitors of the power supply were replaced with new ones. The black and red binding posts on the picture are not original. When I removed the case, surprise... the original binding posts were inside in a plastic bag, tied to one of the chassis cross ties. This is the kind of detail I really appreciate.
