Atwater-Kent cap replacement advise needed.

[HiFiCanada]

Anyone have information as to get the caps out of the Atwater-Kent model 40 power pack? The caps are in the pack as I understand and how do I get them out and were in the pack are they. I was going to lite the BBQ and start pouring the tar out into a steel bucket to keep for later, when I need to fill the pack again, that is, if I should fill the pack again.
Not to worry, I am a welder fabricator, so I am use to fires.
Any photos would be helpful on how to do this.
I first thought that the caps were in the cans on the radio, but I guess those are not the electrolytic caps for the power supply, that I need to be concerned about.
The radio works, all the tubes light up and I even got a 455kc squeal with my RF generator near the radio, so the transformer is good.
