Hybrid Combo Amps

A tube power amp may be fed by a solid-state pre-amp circuit, as in most of the Original MusicMan Amps, Fender® Super Champ XD and the Roland Bolt amplifier, which is thereby classified as a “hybrid” amp. Randall Amplifier's current flagship models, the V2 and T2, use hybrid amp technology. Alternatively, a tube pre-amp can feed a solid-state output stage, as in models from Kustom, Hartke and Vox. This approach dispenses with the need for an output transformer and allows modern power levels to be easily achieved.
