The Audion Sterling can take EL-34, 6550, KT88, KT90, 6L6 and 7027A power tubes, according to what I've read. This applied to the discontinued Sterling - I don't know if it holds for the new Sterling line.

Sonic Frontiers SFS40, SFS80, and except for EL34 the SFM160. I not aware if the latest series allowed this.
Jadis JA30, 80 and 200. I believe that some Cary amps can use multiple types of tubes, and the Rogue amps can take either KT88s or 6550s, not sure about other types.
Research Quicksilver Audio ones. Don't go for minis the large ones are much better.
