I have no idea what you now consider to be wrong with the PSU. Apart
from a resistor that in your opinion runs too hot even though its well
within its rating I seem to recall amidst your ramblings that the
voltage rails are correct?
Yes, they're fine. It's not *my* opinion that this is a poor design! I
posted the schematic to s.e.d and the designers there told me that. I've
said all along I know nothing about this type of PSU so I defer to those
better qualified.
Yes, I read your posts on sed, you didn't tell them this was a Philips
scope, and some replies implied Philips made televisions, jeez.
Philips/Fluke made excellent test equipment and many products beat
Tektronix into the ground but being European never made it across the
pond in large numbers. I've worked in both design and repair facilities
and the folk who couldn't repair ANYTHING were the design guys because
they always spent 3 days criticizing the original design, another week
debating it with their colleagues and then gave it to a repair tech to
fix (in about 30 minutes). You obviously fit into the design mentality,
so good luck and give the scope to someone who will appreciate it.
