I have a leaky electrolytic capacitor. Its a Nichicon 22000 uf 71wv 85 c number 80321. Does it have to be replaced with the exact specs? Can the 85 temp be different, the 22000 uf or 71 wv? If so, do they both have to be replaced? I found some on e-bay but they are for the 1250.Nichicon 22,000 uf, 80 volt. Pioneer part numbers ACH-056. Where can I find the right one or what can be used? Thanks!

Calm down dude... :D
There's dozens of caps out there that'll work fine. Just need to know three things:
1. The diameter of the cap you have, in mm. Standard diameters are 30mm, 35mm, 40mm, 50mm, 63mm, 76mm, and 90mm. The 1080 probably uses a 63mm diameter cap.
2. The maximum height that you can fit in the unit, and the actual height of the cap currently in the unit (for reference).
3. The connection method for the wired running to the cap. I 'think' the 1080 has wirewrap to posts on the 1080, but it has been a while since I've seen one. Regardless, this is not that important, since the only realistic way to connect new caps is by using a screw-terminal cap and adding ring terminals to the existing wires. Edit: Just looked at the manual, and it shows the bridge between the caps as being screwed in, so the stock caps are likely screw terminal already. Still, most new screw terminal caps use SAE #10-32 screws, which will almost certainly be too large for the current ring terminals, so they'll likely need to be replaced.
..and yes, replace both caps.
The SM says the voltage on the caps should be in the neighborhood of 62V, which means a 75V or 80V cap is ideal. The 1080 also has a soft-start circuit to limit inrush current, so you can safely increase the electrical size without much worry of damaging power switches and diode bridges. JEA Capacitors on eBay sells a 35,000uf 80V cap that is 63mm in diameter x 105mm tall, and will very likely fit just fine in the 1080 (contact him, and he'll sell you two caps. Most of his auctions are for four caps). Only modification is that you'll likely have to put new ring terminals on your wires, since the new cap will be using the larger #10-32 screw.
