so in looking at the blackgate supply listing on partsconnexion's website, I noticed that there's more than one series with a part of compatible spec. It appears to me that the choice is between a polar "FK" unit and a "STD" polar unit...

will i want to go with the FK over the std?

I noticed that the mod also described using a 2200 versus the stock 470 microfarad cap...i'm wondering if the extra buffer size would be worth the extra hassle in mounting them...the 1000 and 2200 are HUGE....


Here's their little spiele:

"AC - non-polar, high-current, compact for loudspeaker cross-over applications
C - polarized, coupling applications, compact, great value for money
FK / K / VK - highest technology polarized, rated up to 350V
N - non-polar
NH - non-polar, high voltage
NX - highest technology non-polar
NOTE: Use N/NH/NX series in the most critical coupling and power supply applications
STD - polarized, standard grade, excellent value for money
PK - polarized, ultra compact/miniature size
WKZ - polarized, high voltage, large can, for tube amplifier B+ supply
WK - non-polar, asymmetrical "power tank" design, high current applications"

FKs are worth the extra money.

470uF in one cap is not 470uF in another, hence the size difference amongst other things. If the original is 470uF a Blackgate 470uF would be plenty sufficient. It will probably be the case you may even need to step down in value so you can fit it on the board.

Make sure the voltage of the replacement is greater too...
