Tech Talk - Fender "Champ-Amp" 5F1

This is another in a series of really cool older amps for guitar or harmonica. This is the tweed Fender Chanp.

First introduced in 1948, it sported the name "Champion 800" (with 8" speaker), changing a year later to "Champion 600" (6" speaker) with circuit designation 5B1. It was rated at about 3 watts, featuring a "T.V. Front" style cabinet with two-tone blonde and brown vinyl covering. This style lasted until 1953, when Fender's cabinet style changed to the "Wide Panel" design with a tweed cloth covering. Fender also renamed the circuit the "5C1", "5" standing for the decade (1950s), "C" for the third circuit revision, and "1" was the Champ's circuit designation. The 5C1 circuit was extraordinarily simple, using one 6SJ7 pentode in the preamplifier section to provide a single stage of voltage amplification, one 6V6 beam power tetrode in the power amplifier section, and a single volume knob and no tone controls.By 1955 Fender started putting its amps in the "Narrow Panel" tweed cabinet with a plastic oxblood color grill cloth, and by this time the Champ was officially named the Champ (model 5E1). Through 1957, Champs only had a six inch speaker, but the 1958 model 5F1 featured an 8". The 5E1 and 5F1 circuits used a 12AX7 dual triode in the preamplifier to provide two stages of voltage amplification, and a single 6V6GT power tube to produce about 5 watts. A Champ from this era can easily be dated by the code stamped on the tube chart, by the code stamped on the speaker or by its serial number.
