Talk about going around the world and the thread becoming a cluster**** of info just thrown out there.
This could have been fixed over a week ago, if you just replace those leaky cheap caps to start with.

Leaky capacitors need replacement?

OK, here’s a bunch of pictures: You can still use the radial Nichicon’s OK. Now we can see they were cheap IC axial, so get these Kemet’s just as good as the Nichicons. https://www.mouser.com/ProductDetail/KEMET/PEG124UH2330QL1?qs=%2Fha2pyFaduiIzF561dUvaRbfng7X1%252BD%... Or these 400volters https://www.mouser.com/ProductDetail/KEMET/PEG124VJ2330QL1?qs=%2Fha2pyFaduhcwO2qxWSDEzBRXsrUKlP2qluB... https://americas.rsdelivers.com/product/kemet/peg124vj2330ql1/kemet-33%CE%BCf-electrolytic-capacitor...

I will see if @clio09 has any of the original capacitors he can send me Geez! why go that way, they look like old cheap stuff that may need to be formed, because they are so old, and the same thing may happen again. Just get the better Nichicons I linked to for only a couple of bucks each. Cheers George |
Looking at how tarnished the solder is, the grey color and cosmetics of the plastic wrap on those caps, and how long they are (much shorter now), and that they’ve already leaked, I’d say more than 3 years old. Or they were NOS caps of the shelf that were used and not formed, as electrolytics also have a shelf life and need to be re-formed very slowly when new but old. https://www.youtube.com/watch?v=vA8YksKJSsQ Boring as bat **** voice on this guy Cheers George |
I keep getting 403 errors. Try this it’s the 2nd one https://www.mouser.com/Search/Refine?Keyword=33uF+350v+105c Cheers George |
Ok, thanks, will do! I have a bunch of soldering questions but I will do a lot of research online before I try it out on the amp. If anyone wants to help out:Sorry to be blunt Shawn, for you to ask these questions, this job is not for you to do, get someone that is good with soldering, and component id to do it. Cheers George |
I should add I would be most happy to put something in that might last longer.Just get the Nichicons I linked to for $1.13 each, quality cap and will last longer than you and the next owner will probably keep the amp for anyway. https://www.mouser.com/ProductDetail/Panasonic/ECA-2VHG330B?qs=sGAEpiMZZMukHu%252BjC5l7YR8X6v1kBION9...

If those pics are with the amp upside down then yes, as the electrolyte in leaky electrolytic caps doesn’t flow uphill. Change with the same value and uF and get 105’C temp ones not 85’C. These top quality Nichicon's will do fine https://www.mouser.com/ProductDetail/Nichicon/UCY2V330MHD1TO?qs=OZVHsXXMeBXRI0EgBUy4uA%3D%3D Cheers George |
