About the only thing a 1/2 wave rectifier is good for is...... it's the basis for a FWD.? ?A FWD? (full wave doubler) is just 2 x 1/2 wave rectifiers in series.?
? Agree 100% Jim. I've got some nice little 3-amp FWB rectifiers. I'll toss the single diode and stick an FWB in, along with a fresh cap.
