The Vinnie Rossi L2i used 6SN7s with a mosfet amp, but it's out of production. Not sure I've seen any others. If you can use separates there are dozens of preamps that use the 6SN7 and dozens of solid state amps of all flavors.
Hybrid Integrated with 6S*7s
Does anyone know of a hybrid integrated (solid-state power, tube pre) that uses 6SL7/6SN7 tubes? I’ve never listened to such and am curious as to the sound. I understand execution/construction is of importance just as much as types of tubes used. Thank you for your time. - Louie
