Original poster: "Richard W." <potluckutk-at-comcast-dot-net> Hi all, OK, I had some other views elsewhere and got totally confused. I set up a low voltage circuit and scoped it. With 7.07 measured on the voltmeter at the output of the transformer I saw 20 volts pp on the scope. Then looking at each diode there was no more than 10 volts peak across any one diode. Rick W.
