Sunfire Load Invariant Amp Filter Cap Replacements

        Is there a Phillips part # on those caps?

        They may have been manufactured specifically for Carver.

         Long, skinny caps (such as Carver seemed to like) can be hard to find, sometimes.

Hi . There is a a philips serial number (3186DG932T150BPA1)  

I have learned how to read these - Currently working on a quote from mouser.com , but this company is very slow to respond and finicky and I'm not counting on them.

Very interesting point about the caps being made specially for carver. The closest to a 9300 uf capacitor I could find at digikey is a 10000uf  150v but these are not stock items even at this supplier.

Someone posted a video of one of these amps on sale with an accompanying video of the old caps pulled out and replaced. I was hoping he might see my post!

     Here's a thought: Two of something around 4700uF/150V (MUCH easier to find), in parallel, to replace each 9300uF cap.

     Just a slight bump in capacitance, which never hurts, in my experience.

     The tricky part is fitment in the chassis.

     If you can find some small enough, in at least 150V and mount/wire them with their terminals facing each other (save some room?); you'll be golden.

     I just picked 4700uF because Newark has 176 caps, of various voltages/dimensions, in that value.

     If they don't have something that fits in stock: get the data and search further for someone that does.

     Of course: there are also a plethora of values that can be combined, to match or exceed the 9300uF.

     Actually: staggered and stacked, four 4700uF caps should fit easily.

     Perhaps four of these would fit, that way:

Thank you for your help and links on this.  I appreciate it.

       Hope some of that helps!

            Happy listening!

Mbrusso, what is motivating you to replace these capacitors? Is there a problem with the sound of the amp? How have you determined the capacitors are the culprit for that problem?

@mingles I just saw your post, so apologies for not responding. The amp is sold now.  I did replace the capacitors and reduced a persistent humming problem.   Several things were happening that were contributing to the issue. Firstly a ground wire on the left channel had broken loose from the solder pad on the left channel board - Capacitors on power supply board were also replaced because several were swollen / expanded. Lastly the clamp screws on the transformer legs from the underside of the amp were relatively loose and tightened down.  Amp is not dead silent but much better than before.
