"These are Ham radio RF tubes, not for audio."

Have you told Altec? :)

812 is more the audio tube vs 811 that is zero bias.

  Altec Lansing 1570B needs cathode driven to make the 811 work.

Or Wavac? Although discontinued, they once offered audio amplifiers designed around the 811. As far as "ham radio tubes", I'm sure the 845, 211 and 805 could be cobbled into that category as well. Yet they're all used in several current audio amplifier designs.
