Amp baking.

Yep. No real need to remove the tubes. They're made to handle higher temps than these ...

I only removed mine because the sticky says to bake upside-down and I didn't want to take a chance on damaging them when placing into and removing from the oven. From the sticky:

"Bake the piece. I know it sounds strange but remove the bottom cover, check for strange deposits of wax or capasitor oil and if none is present then pop it in to the oven upside down. If you can set at at 175 that will be good. The upside down is to allow any moisture inside the transformers to escape. Do it right side up and steam can get trapped and later short out your transformer. The reason for this is that carbon resisters will slowly get moisture ridden and go out of tolerance. This is to get them back in so a couple of hours will take care of that."

So just the first couple times on the variac. OK. Now, what is the poor man's version (as I am definitely that man)? ...

Thanks everyone for the responses. Now I'm off to buy some light bulbs.
