Power-Supply Circuit for the RO Imperator I Amplifier
Two dual-polarity outputs. DC power-supply for the 20W RMS Imperator I guitar amplifier. Includes one dual-polarity +-24VDC @ 1A for the power-amp IC, and one regulated dual-polarity +-15VDC @ 150 mA for the op-amps. Transformer, regulator, and rectifier part-numbers are specified in the diagram. Note: Real output power will like be closer to 25W rather than 20W, but will be at least 20W minimum.
