  Well, I just replaced all the both the BD139s and the BC550Cs on the left side of the board.   Good news: I'm now able to properly set the voltage across R10 on both sides and currently have it at...

I put all the BD139s on backwards and feel really, really dumb right now. Right side of the board is working fine now (R10R voltage is 200mV), but the left side is all out of whack. Upon power-up, the voltage across R10L spikes up to...
