Fender Princeton & Fender Princeton Reverb

Introduced in 1947 and discontinued in 1979 the Fender Princeton, and Princeton Reverbs are highly prized amongst guitarists for their great tone as recording amplifiers. Mesa Boogies MK1 was a heavily hot-rodded versioon of the Fender Princeton circuit. The original Fender Princeton used a 6SL& dual triode tube in the pre-amp and a single cathode 6V6 beam power tetrode configured for Class A operation. In 1961 a single 7025 dual triode was introduced into the pre-amp and one 12AX7 and two 6V6GT cathode tubes in Class AB push pull configuration.
