I’m working on a Pioneer SA-9500 amp that’s fully functional, but the owner wants a new power switch. Years ago, the original was replaced with a toggle switch, and now they’d like a push-style switch instead. I’ll also clean all the controls and switches, and I’ve made a list of electrolytics. For those, I’m going with Chemi Con since most of them are already that brand. Two of them are 470µF at 80V, and I noticed Mouser has one with an ESR of 36 mΩ at 1.65A ripple current and another with an ESR of 33 mΩ at 2.4A ripple current. Since they’re in the power supply, I figure the higher ripple current is better, right?

I will up load some photos of the Ampifier and my progress one thing I did notice on the lower tone board there is that nasty word  "Tantalum capacitors" also some the electrolytics are Sanyo brand .

Here is that Photo of the Amp !
