Help with Univox Guitar Amp

I have a Univox Amp I purchased off the back of a guy's truck. It powers on, but all I get is a hum output. I attach a microphone or guitar cable to any of the inputs and *nothing* changes the output sound. The volume control doesn't change the level of the hum output either. I should say, I've been around guitars and amps for about 20 years and the output of this sounds normal, not necessarily a "hum". It soulds like a normal amp with the input (guitar or mic) turned off. I've tested all transistors with a VOM and they seem OK. I've cleaned all pots/boards contacts with contact cleaner. I do not have a o-scope or a signal generator, so I realize troubleshooting will be difficult. I do have a schematic. My question is this: Do any of you have advice for troubleshooting this with just a voltmeter?

your welcome :)

i forgot to add: back when capacitors looked like dominoes with colored dots... and were just as often called condensers.
