The Rockman 220 Power Amplifier was initially the Rockman 160 Amp. Both were manufactured by Randall Inc. model RM-80. The Rockman face plate was the only change to the amp. On the rear panel of the Amp there is a Constant Current / Constant Voltage switch. This acts like the Rockman 500 rear plate EQ switch.
