The Channel A and B 1/4" inputs slide right in and are like barely making connection.

It's only with tube power amps that we run the risk when there's no speaker load. What happens with a tube amp is that having NO speaker load is basically showing a VERY VERY VERY high impedance load since air is a very high value resistor. The output transformer can then become unstable and oscillate at inaudibly high frequencies and at extremely high power levels to the point of actually burning out the transformer. So anyway, for tube amps, never run them unloaded. With transistor amps, it just doesnt matter at all.
