Description
Split-rail unregulated amplifier power supply. Main rails typically +/-63 VDC, auxiliary rails typically +/-22 VDC; these are separate positive/negative rails, not a continuously adjustable single-output voltage range. Manufacturer 1200 W rating is for the specified 20 Hz audio load, not an unconditional continuous bench output. Manual 115/230 VAC selection, not automatic universal input. A100, A180, A400 and A700 versions differ. Verify compatible module, cooling, mains safety and current OEM access.
