Just a few comments.
1. The +300 volts is generated on the video board. The potentiometers
for brightness and focus are located in the power supply for
convenience. There is no +300 volts present when the power supply is
out of the Lisa. If you look closely at the power supply board you will
no

I did some more checking after letting the PSU still all night.
the +5 standby reads 5.4v
The +5 reads 5.6v the FIRST time it's turned on. But, If I cycle the AC, it
goes up. By replugging the PSU a few times it went all the way
Ok, I'm doing this from memory now...
The 5v standby was giving 5.xx volts
The +5v section was giving 7.xx volts.
The +12v section gave 13.xx when power was first applied, then faded to .08v
I guess I like giving contridicting information :o

Hi Jason,
> The 12v line starts at 7.5 then falls to .08v.
Ooops ?! That's a different voltage compared with your last mail.

Well, that's right, (and exactly what I wrote yesterday) but this diode is
placed in the 5 V Section not in the 1
