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.
Be aware if you hadn't insulted me with that "get a life" quip in response to fair critique of the state of the set in the pic you would have gotten a much flatter response there after. I'm no bully, but when someone randomnly slaps me in the face I feel strongly inclined to return the favor...
