Terry, thanks for your reply.  I probably did apply AC to the cap(s).  I converted the single three way cap to three new smaller cans.  I'll check them and replace as necessary.  I did a messy job anyway with all the leads being bare.  When I was checking voltages the tip of my meter lead did touch one of the + cap wires while I was checking the filament voltage and the pilot light came on several times before it blew.
