When I built the Moog filter, I used the Vbe matching method suggested
by Moog. But now I often just use my multimeter to match hfe's when I
need a pair. I really don't know if that makes sense at all. I'm quite
sure that it's not the same, but the parameters would be dependant on
each other somehow ... anyone who can tell me exactly?
