Here's a look inside.
21FJP22 work up after a couple minutes and tests like new.
Yoke, degaussing coil and grounding wire were found disconnected.
All the tubes except for horizontal / HV stuff are original GE date late 1964. All test like new.
6JS6, 3A3C and 6EL6 are RCA branded.
Tried a slow power up and quickly realized the is no B+. Only the filaments are getting power. Likely the circuit breaker is shot.
Trying to pull the chassis right now.
