Sunfire Load Invariant Amp Filter Cap Replacements


If anyone has successfully replaced the filter capacitors on this amplifier, would you kindly share the specifications on the new filter capacitors?  Original filter caps I am looking to replace are a phillips 9300 uf 150 v x 2 capacitors. Sourcing capacitors with the same dimensions is proving to be a bit difficult (not a lot of room to work with in the mounting area. Thank you kindly.

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!

@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.
