6V6GT vs 6GB6G

Top Caps are a real down side for audio amps, as it means an ugly high voltage wire needs to be run above the chassis. That’s a reason why 6L6 6550 EL34 etc are more popular that their T.C. counterparts.

Apparently, after WW II, the military changed from 807 to 6BG6. Most beam power tubes with 6.3 V, 0.9 A heaters are 6L6 with slight variation.
