That is a very interesting idea I had not thought of! Thank you!Why not a manley snapper mono amps 110w from 4× el34 with a much better drive stage ecc83+ecc 182/5867 tube that kicks.
Manley SNAPPER® Power Amplifier — Manley Laboratories, Inc.
The SNAPPER's 100 Watts at full power across the entire frequency band from a quartet of EL34’s in a fully differential circuit topology is only achievable with an impressive 19-layer output transformer designed and wound by us here at Manley Labs, of course.www.manley.com
I assume these are Class AB, however.
