Default Big tubes thread

I'm building a 6c33 these days. I't huge compared to most tubes used in audio...and also it's cheap and has tons of power.
Next i might do a GU-50 PP UL.
I like these big russians tubes, they are not so common, they look great and they cost a fraction from the price of A's or B's .
What's your favorite "not for audio" tube?
