This was the second Paul Rivera designed Champ. It was essentially a Champ II with a second, lead channel and reverb. These are great amps!

The Super Champ used a 12AX7 for the first and second stage preamp, a 12AT7 for spring reverb driver tube, while a triple-triode 6C10 were used for three functions; one as a third stage preamp for even more gain, one as the phase inverter (instead of two for most class-AB circuits), and one as pickup tube for the spring reverb. When the volume knob is pulled, singals from the 12AT7 is routed, resulting in higher gain. Two 6v6 power tubes provide it with 18 RMS watt.

The Super Champ was made until CBS sold Fender in 1985.
