Can't remember what the big ceramic jobs are that are still in
storage, 3CX2500s I think. Stock tube for the 21E. Think they draw 7
amps or so.

Isn't a 6C21 basically a 450 rated for pulse service? Can't remember
the mu, maybe medium, between the TH and TL?

Don't forget to adjust for elevated line voltage.

We'll sort this all out at the Friday night AM Dinner @ NEAR-Fest.  :D
