Today's Mystery Guest (RCA CTC-4)

[Electronic M]

On my CTC-4 I was able to get away with not cutting the skirt and instead use a modern anode lead salvaged from a 90's BPC set and a few layers of thick plastic ziplock bag type material stuffed between the skirt and the HV suction cup. Back when I was active with that project it did not seem to allow any arcing or corona.

I feel it is best not to cut or modify any of the original mounting hardware as you never know when a good 21AXP might surface. Going with that thinking I saved the unmolested bell insulator as is from my set and refrained from cutting the HV lead to have the plug. I was able to make a decent HV plug by striping a good length of spare HV cable folding the wire neatly and tinning the strands together with solder....There are better solutions to the plug then I implemented, but my way does work.

With how perfect your set is I strongly encourage you to not do any thing permanent to mount a different type of CRT which may end up only being a temporary substitute.
