Verified · 87/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Fender Bronco AB764 is a budget-oriented blackface/silverface-era practice combo sharing the basic single-ended 5W topology of the Champ but with the distinctive Bronco cosmetics introduced in the late blackface era. Like the Champ, its single 6V6 produces warm, touch-sensitive breakup at manageable volume levels. An affordable entry point into Fender's tube-amp lineup.
