Back in the mid-1980's, I had a Hafler DH-220 amp which I wanted to modify myself. I went to a local computer parts supply dealer, and got a pair of high quality computer-grade power supply capacitors that were twice the capacity of the stock filter caps in the Hafler. This mod made a really major improvement in not only the deep bass response of the amp, but also made some improvements to the mid-range and upper frequencies. I was able to get the replacement caps at wholesale price -- had these caps been part of the stock Hafler amp, it would have increased the retail price of the amp by a factor of 2.
Output filter Caps
If an Amp has 2 22,000 MFD output caps, what would be the advantage to adding 2 more identical caps if any? Sean, I know you can answer this one. I am using a Hafler DH500 that does a pretty good job with output but have heard that Doubling up the output caps can give some reward. Let me know guys and thanks.
