Default Any Denon techs out there? Denon POA-4400 with no power

Just picked up a nice pair of Denon POA-4400 amps.

Problem is they won't power up.

Seller claims that he ran the pair, then one quit on him about a year ago, so he just used the one
(yes, I know they're mono blocks, but...).

The second one gave up the ship about four months ago and both of them were just sitting on
a shelf when he decided to sell them.

Picked them up late last night and didn't have the chance to pull the covers to look inside.

Just wondering if there is a possible common failure in the power supply.

I'll be taking a look at these more in-depth tonight or this weekend.
