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?
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.

Actually: staggered and stacked, four 4700uF caps should fit easily. Perhaps four of these would fit, that way: https://www.newark.com/vishay/mal220213472e3/cap-4700uf-250v-alu-elec-screw/dp/60AK9812 |
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. |
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.
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! |
