Mark,

   You might broaden your search to include the VT-25, VT-62 (801), the 10,
and 10Y. The 10 family tubes [10, 10Y, and 801] are old triodes, designed in
the 20's, and built through the 40's. They feature thoriated tungsten
filaments. All these share the same base, and have 7.5 volt @ 1.25 amp
filaments.

Do you have the type 46 tetrodes (3) as well for the audio section of the
BC-223?

This data sheet has the BC-223 modulator in the application section:

With all this talk of tubes and good will toward men...

If anyone has a pair of 801As they want to sell or trade, I need a pair
to get my BC-223 on the air. It's cleaning up nicely and very soon the
801s will be the only thing holding me up. Thanks!

73,
