GE A-66 new refurbish job

[de.facto7]

Greetings!

I just opened this up today and it's certainly new ground for me. The oldest thing I have redone is a '72 Sansui stereo amp receiver. This is really amazing. It's Oooold! Any input would be greatly appreciated. Some things that come to mind are what not to use for chemicals if any. I'm not sure if it's OK to use Deoxit or denatured alcohol even. Some of these parts look more like Halloween candy. (BTW, notice my snack in the upper right hand corner of the first pic.) Should I replace the caps with modern electrolytes or go to polyprope or???? Other parts I have never seen before; I have no idea what they are. But I'll go a step at a time.

Any help? 'Looks like fun to me.
