19 tube should be fun, I'd go with around 67 or greater for the plate.

Hello

I am looking for schematics and any other help in making one tube CW QRP
transmitter for 80m band, BATTERY operated. I think about 3s4t or 1t4t
(DL96, df96).
What is minimal anode voltage (typical is 67,5v) which I can use with
this lamp?
