Transistor Vbe Matcher

The general consensus is that matching the Vbe of transistors under constant current to within a couple of millivolts is a good way to find Matched Transistors that will function well in log convertors and other non-linear circuits. The testers here are based on the matching technique shown by analog synthesizer pioneer Dr. Robert Moog
