Can I Use One Channel Of A Stereo Power Amp?

what's the theory behind a dummy load? if there is no input, there is no output except some cross talk that made it into the unused channel which is minute. if using dummy load, one would need a fairly high wattage resistor I assumed.

Although not cheap, the MBL 9007 can be used both ways. Generally they are sold as 440 wpc mono amps but they can also be used as a stereo amp. When in stereo mode the power is greatly reduced to somewhere around 130 wpc.

I always use a dummy load on any unused outputs. An 8ohm, 10 watt resistor is all you need to protect your amp from accidents. This, by the way, is more necessary with tube amps than with solid state. I do not know the theoretical reasons for this.
