DOES ANYONE KNOW THE VALUE OF THE CAPS ON THE OLD FOSGATE X-OVER CARDS? IT IS SMALL AND DARK RED IN COLOR AND IT SAYS "473". I HAVE A SCHEMATIC BUT IT ONLY SHOWS AN ILLISTRATION OF THE CARD, NO VALUES OR PART NUMBERS.
ALSO WHAT POT SHOULD I BUY TO REPLACE A DAMAGED ONE ON A FOSGATE 160.4 (GRIND ON BLACK STYLE). IT'S THE GAIN POT AND ALSO COULD I GET A KNOB TO GO IN THEM. THERE ARE SO MANY DIFFERENT SHAPES AND SIZES I JUST DON'T KNOW WHERE TO START. IT HAS 3 LEGS, STANDS UPRIGHT AND SAYS "5K 824K".
THANKS FOR ANY ADVISE ON WHERE TO START!

473 is a 0.047uF cap.
What's wrong with the potentiometer?
The pot may be a Piher PT6Kh-502 if it's 6mm in diameter. You may be able to get them from Pacparts.com. You'll have to call them. They probably won't use the part number I listed. Have the amp in front of you when you call them. They may need the model, the board number and the circuit board designation. If they're 10mm in diameter, mouser should have them.

SOMEONE HAS GOBBED A BUNCH OF SOLDER ALL OVER THE FRONT OF IT. AND THAT CHANNEL IS BLOWN. SO I FUGIURED THAT ALL THAT SOLDER MAY HAVE HAD SOMETHING TO DO WITH IT. I KEEP THESE OLD AMPS FOR MY OWN COLLECTION AND I WOULD LIKE FOR THEM TO BE FULLY FUNCTIONAL AND ALL THE SOLDER HAS MELTED THE FRONT OF THE POT AND HAS BLOCKED ACCESS TO THE SECOND POT.
THE O.D. OF THE POT IS 10.31MM.

This is the closest I see at mouser. You'd have to make an adjustment tool.
Try Pacparts. They may have the original and the shaft.

im at mouser and i have a bunch of .047uf polyester caps pulled up. what voltage rating should it be at?
also the 2sk366s fully insulated fet. i can't seem to find any around. what would be a good sub or where can i get it.
thanks
thanks
For the crossover card, you don't need anything above a 50v cap.
What is that 2sk366 in? Are you sure that's the correct part number?

You didn't state how it was being used but the IRFIZ48 should be a suitable replacement.
IRFIZ48GPBF Vishay Semiconductors MOSFET Power

The KSC2690 is in a larger package but should be a suitable replacement. If you order these, also order the KSA1220. They are the complementary part and can be used when a PNP driver is needed.
i have on hand MPSW42, MPSA06, 2N3904 and, 2N5551. but all the specs seem quite different. i've read around but still am not quite sure what needs to be looked at when subing parts.

okay i have the KSC2690 and KSA1220. they were in such a larger package i didn't think to list them.
there's a guy on ebay sellin' some huge resistors on ebay. 2 ohm maybe around 500 watts or so. would these be okay for a dummy load on the larger amps?
i have a fosgate series 1 4060x that i can't find some of the parts for.
both of these are fully insulated. RFP15N06 this one is used as an output in one of the channels. MPT50N05E this one is used in the power supply. MPT50N05E is what it says in the schematic but in the amp there is a 0N06 in its place.

There is likely a line of numbers above the 0N06 on the transistor's face.
You don't have to use fully encapsulated parts. You can use standard parts with insulators. I typically use the IRF540A for the outputs. In the power supply, you could use either an IRFIZ44 or an IRFIZ48 if you want fully encapsulated replacements.

cool. i already have the IRFIZ48G and the IRF540.
where could i buy the insulators? which would be better, the colored vinyl looking ones or the hard clear ones? what keyword should i search for? i remember seeing them on ebay but i can't remember what i searched for. i already have some of the dow corning paste.
