Images, attached.
Looks OK, but really soft. Like any video above 2 mhz or so is being clipped. Have you tried out the picture after the video detector? If it's clear there then you could work your way back through the IF, or if it's still soft then you know that you need to work on the video amp.

I'd change all the wax paper caps in the IF strip if they haven't been done yet as they are going to be leaky and it wouldn't take much to have those out of the way.

I'd get the tuner connected also. I doubt there's anything wrong with it beyond maybe some dirty contacts.
