There's also the bakelite Motorola 9T1 and wooden 9VT1. I wonder if there are any other
I pulled the knobs, unscrewed the feet, disconnected the speaker (one wire was already loose) and removed the chassis.
I think a 12SN7 is missing. What are the odds the ballast is good ?
I haven't seen this cardboard shield before. I suspect there was some arcing issues between the CRT neck and the metal box.
All the high voltage caps have been replaced, but the rest look original except for the green one.
The selenium rectifiers have been replaced too I think. Look how far they are sticking into the chassis - looks dangerous!
These should be film caps not ceramic. I've heard ceramic caps vary in capacitance as the voltage varies. That will distort the sawtooth waveforms on the deflection plates.
Remember - DO IT RIGHT!
