RO Imperator II: 30-Watt Guitar-Amp Output Section

Richter Original Imperatore II: 30-watt guitar amplifier circuit, Output Section. Precede this circuit with the same circuit as used with the Imperatore I: 20-watt guitar amplifier circuit. This is essentially the same as the same except for the use of a different power-amp IC, and the specification of off-the-shelf power-supplies. Frequency range and gains are largely the same. However, a speaker rated >= 30W RMS must be used. Example: Celestion "Midnight 60" guitar speaker; 12", 8 ohm, 60-watt. Available at Parts Express. Part # 294-1984. 99.00 dollars US. https://www.parts-express.com . Note that the real power output will probably be more like 33W rather than 30W, but at least 30W minimum.
