In Reply to: exactly how is reducing ripple going to increase hum? posted by Mart on July 26, 2003 at 10:27:22:
The problem with making the filter capacitors bigger is that the rectifier diodes conduct for a shorter period of time with increased peak current. Although 120Hz ripple ("hum") is reduced, higher harmonics ("buzz") are increased due to the shorter, higher current spikes in the transformer, diode bridge, and filter capacitors. The high peak currents may be unhealthy for the diodes. I'd exercise caution.
