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, a 5Y3 rectifier tube and a single volume knob with no tone controls.
By 1955 Fender started putting its amps in the "Narrow Panel" tweed cabinet with a plastic oxblood color grill cloth, 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.
The Fender Vibro Champ was a guitar amplifier made by Fender.
It was first introduced in 1964 and discontinued in 1982.
An updated version was introduced in 2006 as part of the "Vintage Modified" line.
The Champ had the lowest power output and the simplest circuit for all of the Fender tube amps.
The Champ had only one power tube,and the power stage circuit is, typically, single-ended and class A.
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.
In 2007, Fender reintroduced the Vibro Champ as the Vibro Champ XD, part of their "Vintage Modified" series.
Aesthetically, the XD is based on the Champ from the blackface era.
The current look is the TV-front with two-tone tolex and speaker grille cloth of imitation suede.
For a time after Fender's takeover of Gretsch, the same electronics were available with a different look and feel – based on "tweed" Fender amps, despite the branding – as the Gretsch G5222 Electromatic.
