I already own a 5H 600mA choke, all ready to be installed in the P-P amp I'm building. However, that choke is so bl**dy heavy that I'm thinking of trying a resitor instead. A PSUD2 simulation seems to indicate that the ripple would be quite small if I use enough smoothing capacitance. A 30 ohm 15W-20W resistor might seem a bit ugly, but it would be a heck of a lot lighter than all that iron.Just wondering, though - if I use 50uF directly after the 6D22S rectifiers, then a 30 ohm resitor, then 470uF as a reservoir capacitor, is this likely to stuff up the 6D22S? I know 50uF is safe, but will 30 ohm provide the rectifiers with enough protection from the 470uF?
