Just fired up an old RCA Victor black and white television with a CT23
chassis. Took my time turning it on, 1st gradually at reduced voltage,
and then at full voltage only for short periods of time. It's working
perfectly just like new.

The stock HV plug is just a little two prong spring hook with some black
wrap around it and the CRT has a large circle painted with red hv dope.
With the lights off I don't see any corona in the HV dimple area but I
was wondering if I should still add a high voltage boot to cover the HV?

... I remember the 6SN7...

It is safer to have a high voltage boot. It sounds like someone
removed it, and never replaced it...

I thought CT and CTC were color chassis'.

Most B/W TVs of that era had no rubber cup. If there's any corona,
clean the CRT.

Sorry, made a typo in the Subject line. It should have read CT23 B&W.
It has a very low serial number and hardly any use or dust inside it.
Must have been owned by a little old lady who only watched Ed Sullivan!

... If plugging it in doesn't help, turn it on.

I remember that RCA BW chassis numbers of the 1950's were preceded with
KCS. I thought CTC was color. Many of those second anode connectors
operated below 15KV and so except in very humid conditions corona was
not a big issue. I would not worry about a boot. Just keep it clean. If
you catch any episodes of Captain video and his video rangers please
tape it for me...Lenny Stein.
