The Emperor is full of hacks (25MC46Z)

agree with CTC17, the 100uf 450v is a replacement for an open section of one of the filter cans, the other is a Thermistor. Those zenith chasssis that use that style of term strip make for convienent test points, and in this case a quick fix from the top of the chassis (the orig service guy prob did not want to pull the chassis, and since its a combo, did not want to flip it over to get at the service saver plate on the bottom).

since the orig prob was the blue gun, you should test the CRT, then check the voltages at the CRT pins, wiggle some of the demodulator tubes. Scope the grid of the Blue gun at the crt and see if anything is going on. Looks at the screen voltages of the CRT with a vtvm compare the blue to the other two guns.

Careful handing the zenith chassis with it out of the cabinet, there are a lot of parts leads that can short if a part is moved around by handling. I set a chassis down on some soft padding for transport, the padding pushed up, came into contact with a large disc cap, moved a lead into something it should not have been, ended up with a difficult to find hum bar.
