If you "never look at the underside of a chassis once it is repaired" or expect to see a bunch of yellow things, you might want to turn your gaze away. Also, there is no card to tell future explorers not to recap again.

   

   

Besides the caps and most of the resistors, I did have to replace one mica cap that was shorted preventing SW operation. So mica caps do fail at times.
