The +100 primarily set by the pair of 30K and the 22K resistors, and the 6au6 trims the -55 volts. I don't think the PNP transistor, silicon vs germanium,makes much if any real difference, simply because the Zener is a +/-5% part, which means it can be anywhere from 25.5 to to 28.5 Volts. Adjusting R-50 should get the -55 in line. _____
