Roger,
The 6080 (and it's close kin, the 6082) have a claim to fame in the
audio world: OTL! (Output TransformerLess). There is an excellent
example of this in Terman's "Radio Engineer's Handbook", Mcgraw-Hill,
1954.
The idea is to take advantage of the low plate resistance exhibited by
this tube, and stack several in series-parallel to directly drive a
loudspeaker.
Best regards,
Ernst

Only has an amplification factor of 2. You can do nicely with other tubes
as cathode followers.
