Help with Cap Type Identificaton

[John Folsom]

The only caps I would leave in a set would be the ceramic discs. All others really should be changed out for new ones. Otherwise you will be back in the set in a few months looking for that failed capacitor you did not change out.

There is a bunch of mica ones in there. As I remember reading these are as good as ceramics?

Micas are more reliable than paper, but I have found bad ones from time to time. I usually leave them alone during the first go-round and then try the TV out.

Horizontal circuits are where I have most often needed to replace micas. I'd avoid replacing micas in RF or IF circuits unless needed, as "shotgunning" them without a specific reason may force an unnecessary realignment.
