Curious what the amperage rating on the old PS-131 unit was. The first one you just linked says "12 VDC 1.25 AMP", but on the PS-131 page, that text line has been replaced with the words "Sold Out". So I dunno if it'll be close to the PS-131's performane or not...

1.25 amps is right on the edge of the spec we need. I wouldn't go for the 1 amp unit (the second one you linked) because that probably can't handle the draw the player will put on it.
