- I've got just about all of the parts for my 2 x 3-500z amplifier except the plate transformer. I haven't been able to find one of reasonable size and weight inexpensively, so I'm thinking about buyin

- ? An important factor with capacitor-filter supplies is the winding R of the transformer. Since FWD supplies require only half as many turns on the HV secondary winding as do FWB supplies, making a

- ? good point. . . IOW more copper and less paper. But isn't the transformer utilisation factor worse with the doubler, leading to higher peak currents, and so more loss? OK, so resistance is less, b

- ? So it would seem. . However, the decrease in R with half as many turns required is better than what one might expect since fewer layers of paper lets one use a bit larger gauge of wire than would
