Made in February 1961 Fender Bassman, almost all original amp head; a super clean example with thunderously loud and articulate tone, beautiful blonde covering and oxblood grille, has original power transformer, choke, and later Fender output transformer. This has the 6G6 circuitry and is a non-GZ34 tube rectifier equipped model even though the tube chart prints so. It could be a transitional model during that year. 

*Export model; with voltages selectable between 200V ~ 240V internally. A step-up transformer is necessary for operation outside of these selectable voltages.
