I like the idea. 
Thanks for sharing, Russ.
Years ago I found that a 1G4GT worked great as an 01A substitute, with a suitable adapter. Only thing is, they require far lower filament voltage (2 volts), so you have to make a complete set of adapters for a five tube radio.
I have a few three dial sets including an AK 20 Big Box, Super-Zenith VIII and a Slagle, so I would like to try the 6C4 tubes (with adapters) sometime for myself.
