i have a b-52 half stack

whenever i turn the amp on it goes in and out of the volume it's set too till it's fully warmed up and when it is the tone is all screwy

could it be one of the tubes?

should i take it to guitar center to have them look at it?

EDIT:

yes i use the standby

i just flip the power on and wait a few minutes to let it warm up

See, you need to let tube amps warm up a while before you begin playing on them. Otherwise, it'll damage the tubes. I'm sure about the specifications of your amp specifically (because it often varies with amps), but you should generally turn on the main power switch first, let it sit for a few minutes, then turn on the other switch.

and reverse the process when shutting down..

you could of damged a tube or have a micrphonic tube either way needs replacing
