Aside from pulling the bridge rectifier out and testing each diode, is
there a way to tell if one of the diodes is open? I'm trying to visualize
what having one open diode would do... wouldn't it become a 1/2 wave
Here is what the ripple looks like, measured at the big filter cap:
It's clearly 120Hz, about ~300mV P-P. The PS is putting out the correct
voltage. Ripple on the regulated output is nil.
