This should be something simple although I am obviously missing something. I have two power supplies, one good, one bad. I am measuring the DC voltage on the rectified side of the bridge rectifier. I am measuring between the - and + points on the rectifier. On the good power supply, I measure 330VDC and on the bad supply, I measure 336VDC. They are similar but my questions is, I thought they should be in the area of 150-170 VDC. What am I missing.
When I measure Emitter-Collector(Q1 and Q2) on the good one, I read around 155VDC which is what I expected. On the bad one I read 5.5VDC and 320VDC (Q2 and Q1) so I suspect the problem is on the Q2 side of things.
Just curious about rectifier voltage.
