Ask him about is neumonic device from the military for remembering resistor color codes. B B R O Y G B V G W

best teacher ever.

Check to see if the capacitors are bubbled at the top (make sure they are discharged), and yeah as garberg said, resistors are color coded (you guys should know this by now, or you shouldn't even be attempting to open the amp up), check the powersupply as chuck said;

Look at the soldier connections from all the various connectors, make sure they are all good....

but good luck finding any good diagrams....haha

it well power up but sends nothing to speakers we are going to do a alot of testing tomarow in class
