Power-Supply for the 150W Stage-Amp or 150W PA-Amp
Power-supply circuit for either the 150W Stage-Amp or the 150W PA-Amp. Provides three outputs; one regulated dual-polarity +-15VDC @ 150mA for the op-amps, and two unregulated dual-polarity +-27VDC @ 2A for the power-amp ICs. Experimental circuitry. Breadboard test before soldering. Heatsink the regulators. Shield the transformers from the rest of the circuitry. House entire project in a grounded metal enclosure.
