Thanks! A couple more Q's.

Thanks, Mike. JOC... what does this "switching noise" sound like? Is it in the audible frequency range? Is it possible to shift this noise to a frequency which is more harmful, by using the wrong valued bypass caps?

In most amps I've seen, the main PSU diode bridge and bias diodes are removed from the main circuit board. My understanding is that RF noise generated by the rectifier board can be picked up by the main board. I'm not sure if this applies to modern fast-switching diodes, or not. Some amps even have metal shields around the rectifier board. Seems that this issue should be approached as diligently as bypass caps (or inline resistors).

Thanks, again!
