Well, gathering parts for a tube matching rig a la:

Would you folks suggest any additional features which may be useful down the pike?
I am planning for higher rated plate and filament transformers, should I ever come into some KT88's...
Also adding noval sockets for 6BQ5...

Looks good.

I'd add either different switchable transformer taps or build it for, say, 600V and add a MosFet to pad it down as needed.

Why not just use a variac?
Filament supply is separate.. I'm using a separate bias supply also..
