monitor is WG 19K4675 (tube is 19VMBP22)

what if it has no vacuum and you turn it on? any dangers/risks?

i ask this cuz the tip of the neck is broke off (no biggie, quite commonplace),
but one of the pins of the CR-23 is also broke down to the core (pin# 13),
which isn't even used in the circuitry or neck board.

i know orange glow = good, blue/purple glow = bad.

BUT what if you turn on the mon and it has no vacuum prior to testing it on a rejuv?

does it explode? implode? crack? zap you with 30kvdc? nothing?

i think you mean 19K4675??
btw nothing really bad just internal arcing, kind of like lightening in the tube so to speak from what i have seen. it won't get you but don't leave it on. video tape it just in case....;)

haha thanks! i typo'd that, fixed in my orig post.

and also good advice. i was just scared not knowing what the result of a un-vacuum'd
monitor would do. with that, i'll be sure to plug it into my sencore rejuve first to do
some initial testing of the basic specs, including vacuum. then hook it up to the TPG.
