21CT55 Screen-Shot Test

[Tomcomm]

After much confusion I have identified my infamous 21CT55 photo as a very
early work in progress attempt to replace its FBT. I agree that both CRT
anode and focus rectifiers in the photo are 3A2's, dated Dec 19, 2010.
The original 21CT55 uses 2 3A2 in a voltage doubler HV CRT anode circuit.

The latest FBT replacement photo, dated July 5, 2011 clearly shows the
focus rectifier as a 3A2 mini, and the CRT anode is clearly a 3A3C octal.

Apparently my 21CT55/ CTC 20A hybrid still uses this scheme today, Feb 3, 2019.
Too bad there was so much vicious discussion. I don't do well with bullies.
