I really don't like chokes. I find that in my bad luck, they introduce some noise. I can live without the benefits of a smoothing choke. I like the sound of a resistor. Seems to "sing" more under higher current demands. I like the Dale Aluminum housed wirewounds(25 Watt) that you can screw into the chassis. This acts as a heatsink. They also make great cathode bias resistors, too. Jason C. Arthur
