It is adhesive used to keep the caps in place, usually during machine soldering. It starts out yellow but as it ages it becomes brown. It also can become conductive and corrosive. Best to remove it before it creates problems.

I recapped that board and is dry adhesive. I just scraped it off and installed new capacitors.
I’m not worried about any vibration that might fatigue the leads of the caps.

There is an orange material filling the edge-space between the Rectifier B Board and the end of some cylindrical electrolytic capacitors. This occurs only on capacitors along the outside of the mounted-capacitor array, upward and sideward (front-back), of several electrolytic capacitors on the vertically mounted board.
