A 1957 Fender Vibrolux Tweed (5F11 circuit) in exceptional original condition. This amplifier retains its key factory-original components, including the original transformers, original Jensen speaker, and a complete set of original Astron capacitors—an increasingly rare feature to find in amplifiers of this era.
With a tube chart code GH (July 1957) and serial number F-00284, this example dates from the early production years of the coveted 5F11 circuit. It offers a remarkable combination of the Tweed Deluxe's rich tonal character and the Vibrolux's unique tube-driven vibrato. Rated at approximately 10–12 watts, it is equipped with its original Jensen 10" Alnico speaker (EIA code 220721).
This amplifier retains an exceptional level of originality:
To ensure reliable operation, the electrolytic capacitors have been professionally replaced with modern components. However, all original Astron capacitors have been carefully preserved and are included with the amplifier, maintaining its historical integrity and collector value.
Specifications
Produced between 1956 and 1960, the 5F11 is widely regarded as one of Fender’s most refined tweed-era circuits. While sharing much of the architecture of the legendary 5E3 Deluxe, it incorporates a unique tube-driven vibrato and a negative feedback power section that provides greater clarity, definition, and headroom.
