On the diagram for Q602 (PC602), it clearly shows E going to ground. Is this the top left transistor on PC602 in the image? I have a simple multimeter; I understand how to test to see if they are good, but determining collector and emitter is difficult.
If you look at the plastic case, the outer circular edge has a flat spot. The lead that is closest to the flat spot is the Emitter. The metal TO-39 case transistor has a small metal tab that sticks out from the edge. The lead that is closest to the tab is the Emitter.
The center lead of the three is the Base and the other lead is the Collector.

Thanks, guys. I just need to wait for an NTE108 to come in for PC702 (somehow I ordered something else), and then I should be good to go. I've left the new 35A bridge rectifier in place, and right now I have the new filter caps. I'm thinking I should put back in the old ones (they were fine), at least until I know everything else is working. Checking my work on PC102, since the transistors there might not be in the right place.
