Re: Amp that could get close to this tone?
I tried a set of KT-88s in my 2555, but the tonal differences were pretty minimal compared to EL-34s; a little bit louder and a bit less bright at the same settings.
I have only ever ran EL34s in my original Jubilee because the bias range is too narrow to bias up non EL34s without breaking out the soldering iron. The reissue 2555 can run a wide variety of octal power tubes with a user service-able biasing system, though.
