I'm taking the liberty of grabbing people's posted links and comments and adding them to my Web page. Of course contact me at my site (as some have) accordingly or with more notes, or to ID some of the photos. I've added a few more photos from other folks, as identified.

expected level and was is similar between the caps and segements?
Have you plugged it in and did you get a super-nova?

>expected level and was is similar between the caps and segements?It seemed different between segments. In each case, one segment had higher leakage - around 20mA - after reforming, while the other segment was lower, around 2mA.I plan to trace out the schematic if I can't find one online or amongst my DG stuff, and see how the segments are being used. I'm guessing that one segment is 'stressed' more in use than the other within each can, and when I reassemble the board I might reverse the segments so the stronger ones replace the weaker ones.>Have you plugged it in and did you get a super-nova?Haven't plugged it in yet. I want to get a better 220V supply to my bench first. That little gray transformer I had with me isn't up to the task of powering the Nova.If I do get a super-nova when I power it up, you'll probably see the light in the sky all the way from Maryland...-Dave

them of course; you can do likewise.
Got around to posting my PDP-8 photos of the repair, as conducted
by David Gesswein mostly:
hard to believe it was only two weeks ago. Busy month...
