Life of a PS Audio PowerPlant??

The PowerPlant to which Tiofelon refers will overheat. That's the main issue with it; and with the P500, as well.

They tend to overheat even when not loaded with more watts than recommended, and the cooling circuit tend to fail. That's been my experience with two P500 units that I have owned. I traded-up to the PPP, and have had zero issues with it. The PPP is very quiet, and doesn't overheat.

The caps on the P 300 will go bad after a number of years, which happened to me. Call PS Audio, and arrange to send it to them, and they will completly restore it for $250.

My PS Audio P600 is doing fine. I keep it lightly loaded, so it is not stressed at all.
I would think left on 24/7/365 with the same load 24/7/365 it will last many years as is.
I bought it used two years ago.
I had a PPP and sold it to buy the P600 to get it's unique output frequency adjustment available with an optional boeard..
That is the primary reason i bought the P600 in the first place.

My experience is the same as Islandmandan's.

I have had mine since they first came out and it still works like a champ. I am knocking on wood since I said that though.
