If breaker is tripped, would the gun and channel still light? I doubt it but who knows.

Most 60s color sets the breaker was between the B+winding and the B+ rectifiers so if the breaker tripped you'd loose everything except the heaters and dial lamps.

Learn something everyday, lol. I'll look for the s cap tomorrow. Supposed to rain so I'll be in most of the day.

I checked breaker today and it just pushes in and back out. I've included a pic of its position. I broke my glasses the other day so seeing anything close up is out of the question. Turned set on today and same thing. Just heaters and channel. Turned off for a minute and tried again. This time, I hear it try to start up with kind of a bong sound, but still nothing but heaters and channel, then a foul burning smell so I turned back off. Pulled back but couldn't locate smell origin. I couldn't find the s cap either. I'm including 12 more pics. Hope this helps.

Went down to the dungeon today. Pulled Sams 1949-1

Breaker on sec of transformer & kills the 143 source. PS is
copy of Zenith with the oil cap
S cap is C702 .00155 mfd 1.5 KV P# EP18X137 Its behind
the HOT & a few inches away.

First checks are
Reset breaker.
Check for @143 VDC at case of HOT
" " " 24 VDC at PGRL5 of the little rectifier ( red wire ) board.
For meter GRD use the CRT grounds.

Burning can be a lot of things. You have to go step by step to narrow things down. Usually the FBT or vert module on these & do it without spending $$$
