Phoenix Gold Phorum

wanted to share a pic, after changing the caps in one of my ms2125's.
Original [as you probably all know], they are 2200mfd, and tend to leak and are likely to fail, or catch fire.
I've changed them, with advice of dr. fosgate [eric]. These new ones have a capacity of 6800, but that should make no difference.
technology seems to make it able to house such a capacity in the same dimensions as they used to make the 2200's , in the 90's.
Very satisfying job, knowing that it will lengthen the usable lifespan of the amp a lot.
Don't you just love the SUPERB quality of these amps?
got to go, have to take my medication, against droowling on it again.

hey i used 8800 uf caps in mine.
also changed rail caps to 50 volt caps.

heywhat rev board is that.
probably a "c"


edit,,,,03/24/07
i used 8200 uf not 88

Nico, do caps require changing due to age or just use? Who is DrFosgate? I think I may have seen him on talkaudio?...

This is the article which has shown many how to do this…

The capacitors on older PG amps, M, MS, ZX, maybe others tend to catch fire with seemingly no reason. They leak their internal fluid and internally short then burst into flames. The end result is often an un-repairable amplifier.





It is not a good practice to increase the voltage of your capacitors unless you are unable to find a suitable replacement in the voltage you require. The higher the voltage capacitor, the less capacitance it will have at the operating voltage of the capacitor. For this reason it is best to get it as close as possible.

hi Paul; you just got answered by the master.....
I have nothing to add here!
[exept also to warn you for the time-bomb-capacitors in those amps..]

Unless your name is Dr Fosgate, and in which case you just recreate the board and fabricate new circuit traces

I ordered some original style Panasonic caps (but larger capacity) for all my BNIB PG amps. I'll be swaping them over in a couple of weeks before they see any power, to be on the safe side. Thanks to Dr.Fosgate for these guides.
