The LM723 is at the upper left corner of the board with the adjustable current limit resistor to it's immediate right. The adjustment wheel was sealed with a dab of adhesive. I measured the resistance at 290 ohms then gently pried the adhesive off the resistor. It varies from 0 - 420 ohm. I wonder if it's adjusted at the factory to fine tune the circuit, sealed, and then shipped? Maybe my issue is the power transistors?
