Stupid Question: How to take out tubes??

I know this is a stupid question, but i want to know how to take the tubes out when replacing them. I opened up my tubed preamp yesterday to replace some microphonic tubes but I wasn't sure how to do it. Do I just pull the tubes straight out, or is there a release lever on the tube socket. I dont' want to mess around with it unless I know for sure. The tubes are 6922. Thanks

Fingerprints and residual oils: The reason is that the oil on glass versus clean glass alone causes differential heating, and a more unstable environment, and the tubes (or halogen bulbs) are potentially prone to a shorter life.

Just my $.02.

Fingerprints on tubes.. Bogus nonsense !!! .................

Vacuum tubes are not halogen bulbs. You can get your grimy oily fingerprints on them all you want with no ill effects.

Just wiggle the tube slighly while pulling upward on it to remove the tube. It's not rocket science and again, don't worry about handling vacuum tubes with your bare hands - unless the tubes are still hot!
