Amps that will accept wide variety of tubes?


Any amp that will take El34, Kt88, Kt90 and 6550..? Thanks!

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.
Sonic Frontiers SFS40, SFS80, and except for EL34 the SFM160. I not aware if the latest series allowed this.
