I found a similar circuit and copied that into my power supply. Now I
can't hear it in the radio. I'm pumped <grin>. $10 for the modular units
seems pretty reasonable to me. I'll be looking at those for future
problems a dn Have made notes about various brands. The one I ordered
(and still not here) also had glowing recommendations. I'll report
results for that one when I get it. I have been avoiding running my
backup srver (backs up personal data for the family's computers) because
the power supply is on the light weight side. But it's quiet.
