I was bored late last night so I decided to clean this set up a bit.
Took a while to soak all the goo off the faceplate and CRT but I got it done without any mishaps. The face is really clean except for some faint streaks across the front that should buff out.
I tried a slow power up as well, there was some crackling from the ballast, either electrical or mechanical from dirt burning off, got a faint tickle of HV and some scratching from the speaker when I touched the cap of the 1B3 but nothing on screen. Nothing smoked though.
The CRT is a Hytron replacement and the volume Pot has been replaced also so this set has seen a lot of use.
