Power Supply Caps
It does make a difference, doesn't it??
The caps will not drawl much more voltage (there may be a peak voltage...I'm not 100%, most likely!), but they will need larger amounts of energy to fill to capacity. This is a problem at start up. Ever hear the thump in your speakers when you power up some amps? That's where the problem starts, then it goes back to normal. All that energy gets drawn to fill up those large resevoir caps. (This is the argument for leaving you amp on all the time. But some think that leaving it on will degrade parts just as well, so which is it? I don't know. That's why it's an argument!!) The break down of the rectifiers happens over time. The bridge should be at lease twice the secondary voltage coming out of the transformer, and maybe 5 times the current drawl.
I keep refering to Nelson Pass and Pass Labs. They have a great article on his "ARTICLES" web page about power supplies. It explains power supplies pretty well. Also, read the A75 article from cover to cover. I learned so much from it.
Oh, one last thing!! Be real careful when working with Power supply CAPS!! I've seen them melt tips of screw drivers!! They can store a voltage long after the power is cut from them!!! It's their job! Find out how dissipate the stored voltage. Anyone know a good value and wattage of resistor to do it??
Great to hear the upgrade helped!!
