Admiral Roundie Something explodes

The cap should come off as one piece, unless it's broken of course.

If it's already loose you should be able to heat the pins with a hot soldering iron, one at a time while gently pulling it on teh side where you are heating it, a little at a time.

if you have a really hot iron 25 watts or better you can probably heat two pins at a time but just be very gentle not to break any of the wires or snap off the fragile Glass nipple that's underneath it.

To check for a white getter you will have to remove the tube from the chassis, it'll be in the area under the Yoke.
Some tubes have a Getter near the high voltage connection on the side of the tubes bell, if you can see a white patch there the tube's done.

If you remove the tube use extreme care not to rip the cap off as it goes through the Yoke, they can be tight sometimes, a little heat from a hair dryer or heat gun can help it go through but don't hit the tube with the heat gun or you could shock it and cause it to break.
