The three position power switch is also the polarity switch. If you hear 60 hz hum, try using the other "on" position.
If you get the reverb working, there is a little flaw(read: "feature" in Microsoft lingo) in the design. Turn the volume all the way down and the reverb up full. This will give you a reverb only signal thru the speakers. Useless but something to play with.
