Pioneer SA-9900 Capacitor replacement

[FRANKPIETTE]

Hello There!

I'm looking at a Pioneer SA-9900, I noticed that on the power supply board there's 2 470uF 80V caps. They're three legged, really not common with three legs, i checked, Digi, Mouser and many more those i found are not available. According to the underfoil pictures from SM, they show them as a 2 leads, can i already be sure the 3rd leg is a dummy? On board the one still on, has its 3 legs are connected to action and no legs on an isolated patch. Anyone had the same problem? What replacement have you used?, If the 3rd leg his a dummy (anyways) i have many 2 legs 470uF, 80 volts caps.

Yes the 3rd lead is a dummy. Feel free to use a standard 2 lead 470uf 80v cap.

I used Nichicon UHE2A471MHD (CAP ALUM 470UF 20% 100V RADIAL) in these positions.

My mains voltage is a little on the high side which resulted in 78VDC across these capacitors and I felt that an 80V rating was cutting it a bit too close so I went to a 100V rated capacitor.
