No 7-digit number to be seen on PS board.
There are three boards on the left, one really small. I put pics of these on Flickr along with the other chassis pics so they can be viewed full-size. I tried my best to aim the camera so the flash wouldn't obscure large parts of the boards.
I'm planning to get a good ESR meter soon, so I'll be doing a lot of cap checking before I even try to start this thing. Who knows what spending maybe half its life in that garage did to it.
