cycle the amplifier with the ~ac mains relay switch on the rear
panel.
In addition, the AC input to each transformer is fused to protect
against excessive current conditions such as driving shorted
outputs. In-rush limiting prevents premature aging of power
supply components during power-up, and switches to off-line
once the power supply has been charged.
Finally, the Nº33H incorporates a controlled clipping circuit that
prevents output devices from saturating. The harsh high-frequency
harmonics generated by hard-clipped output devices are avoided
by the wave-shaping action of this controlled clip circuitry.
