128v at the diode there just before the filters and choke.
Also q212 voltage regulator.... Take a test of the 23v source on the scope, and dmm, that voltage should be spot on, and across that zener diode, should be 24v spot on....
good test for your dmm and scope for dc....

The voltage to and from the regulator (Q212) is correct. I get 23.4V and 24V. Each is only off by .2, but that's most likely my DMM. The scope also showed the proper divisions from baseline for DC.
I thought that 3.5uf canister wasn't soldered in, but it is. It's also 440V. What size resistor will I need to discharge it?
