I've been swapping tube bases on a number of the ancient tubes but no I'm down to the ones where the base is solidly attached to to bulb. Does anyone have a technique that works without breaking the vacuum? These are mostly 199's and a few WD-11's.

Thanks for the link. Looks like I'll be trying heat first, but suspect ammonia is the way to go in the long run.

I have had good results with soaking the entire tube in boiling water. Put something on top of the tube to hold it under the water as it boils, as a lot of tubes tend to float.
