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.

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.
