If I got any dampness in the tube it arced like crazy when I switched it on. That can kill a monitor very quickly. Once I warmed up the air in the back it was fine though.

Oh holy crap... rapid temperature change will kill the monitor just as fast as dampness.  You know why it was arcing when damp?  Because of the rapid expansion of the glass when you heated it up... causing cracking in the seals around the anode due to different rates of thermal expansion.  You were actually killing the monitor yourself.

I take your point about the rapid expansion. But that isn't what happened with my cab. It only arced when I tried to switch it on without doing any warming up. Once I'd left a hair dryer running for a few mins. on the shelf below the tube it was fine. I didn't blast the tube from an inch away with hot air.  :dizzy:

It was arcing when cold because the gap between the tube seal and the anode was wide when cold... then closed when they warmed up.  That is the sign of a broken seal which is usually caused by frequent rapid temperature change and a failing CRT as a result.

I posted a similar question a couple of months ago.  The general consensus is that it's not a problem, just bring it inside and let it gradually warm up for a while before use.  I would say a day or two to be safe.  But I'm just a schmuck who stayed at a Holiday Inn Express last night

ChadTower:

That's pretty much it... ops store their games in unheated warehouses all the time.  Just make sure it hits room temperature at its own rate and don't turn it on until it does.

Whoa wait a min!

i am using a TV in my cab and its in my garage so if it was cold in garage and i power on the arcade. does that cold effect happen?

i never saw anything wrong with my TV when i power on my cab in the garage.
