two D44Q1 transistors. As expected, there is about 65KHz going into the
base of the transistor for the 5V side. However, there is no signal

Hi everyone,
I've been trying to figure out what is wrong with the 12V rail on my
H7861 (BA11-S) power supply. It's showing about 4.2V. The 5V rail is
spot on.
Page 39 of the following schematics is the main part board of the PSU.

I'd get a RS232toWIFI dongle, they're cheap and easy to make a connection
via simple terminal software to an outside telnet target.

I'm reminded of a unit manager at CDC that I worked with for a time.
His first job at CDC as a fresh EE out of UofMinn was to measure all the

This is the first time I've run across a bunch of double-sided 8"

I had a dead 555 on a completely different PSU, so it could be worth
checking. I socketed it when I replaced it so it was easy to replace again.
Also, just because a capacitor doesn't appear swollen or show signs of
