OK, I've been working on the electrolytic capacitors which consist of seven capacitors in three different style enclosures.
The first is a wax cap under the chassis that contains three 10 MFD caps @25 volts. I replaced these with 50 volt caps. I cut the top of the cap into 4 sections with a utility knife so I could remove it without doing too much damage to the rolled lip of the capacitor:
I was then presented with a very hard black tar. I heated it with my heat gun on low to prevent scorching the cardboard sleeve of the capacitor. Unfortunately the tar never got soft enough to pull out, but since the replacement caps are so small I just dug out a little cavity big enough for them:
I set them in hot glue to hold them in place and then finished with brown hot glue, and have since trimmed off the excess heat shrink with an Xacto knife:
