In Reply to: Bypassing diode question posted by Bom on July 15, 2012 at 06:46:50:
Nelson Pass wrote a great article about bypassing diodes and diode bridges. You can find it through a web search. Bypassing a diode with a smaller value capacitor is an attempt to route the switching noise generated by the diode to ground and away from the signal feed. If you replace the OEM diodes with Hexfred soft recoverys or Schottky diodes, you can improve the sound even more. Be aware that you may have to go to Cree diodes (Parts Connexion) to get higher voltages. Also, Hexfreds and Cree diodes are very much more expensive than your OEM diodes. Also, be sure to replace with same (or more) amperage and voltage. To find this, type the part number into a search engine and it should come up with a description of the diode. Good Luck!
