and probably scared the hell out of you and the wife. Are you sure that it wasn't a letter from the "Unibomber" in your garbage that blew up?Staggering sizes of caps in parralel is a worthwhile tweak. Another one is to wire low value "bypass" caps in parrelel across the terminals of the larger value caps. This gives the smaller cap the ability to discharge (and supply the initial power on demand) while the larger cap catches up and supplies the reserve on longer sustained demands.
Depending on the materials used in the caps, some are faster or slower to respond to demands. Larger caps tend to be more sluggish, but have more reserve for larger / longer demands. Increasing these would tend to give give a more solid bass foundation and increased sustain / definition. Smaller value caps are quicker and can smooth out high frequency smearing and sibilant problems.
As was pointed out previously, receivers are major offenders in having weak supplies. Old amps from the 70's and more current designs that are underdesigned / budget cut models can also greatly benefit from these tweeks.
Capacitors can store some hefty voltages and can be quite shocking to deal with. If your going to work on something, unplug it from the wall and turn it on. It will discharge the energy stored in the caps relatively quickly and make it much safer to work on. Caps also have polarity and max voltage ratings to them, so be careful with that also. If hooked up backwards or over-volted, you will get to hear a short but loud explosion like that of a firecracker or M-80, depending on the size of the cap. Sean
