I guess I'll just have to test my theory and buy a NOS 5U4G tube from AES or one of the other tube outfits online.

I guess you could also test that theory by pulling your vertical and horizontal output tubes and seeing if your current draw decreases substantially? I think it's highly unlikely that several 5U4's don't have enough snuff to power the circuits. This company has new 5U4GB for $12. Why not keep the rarer 5U4G's for after you get all the bugs out?
