In addition, the AC input to each transformer is fused to protect against excessive
current conditions such as driving shorted outputs. Inrush limiting prevents pre-
mature aging of power supply components during power-up, and switches off-
line once the power supply has been charged.
Finally, your amplifier incorporates a controlled clipping circuit that prevents the
output devices from saturating. The harsh high frequency harmonics generated by
hard-clipped output devices are avoided by the waveshaping action of this con-
trolled clip circuitry.
