Run capacitor replacement

A separate winding and a two amp fuse for a couple of pilot lights ? Strange ....

Allows for instant on - the winding for the CRT filament can be powered while the set is off. The lamps would need a separate winding.

I have an old stock Zenith - it comes with a mounting clamp as well.

Cool! So these don't go bad from sitting like electrolytics?

Ahh, so that's why there's a separate winding. This set has an "Instavu" switch on the back. I have it turned off though.

Nah - They are hermetically-sealed and oil filled (hence the "no PCBs" label), and are not affected by aging as much as an electrolytic. These types of caps are in most every home air conditioning system - the one in my Rheem gaspack right now is a Zenith cap - put there while troubleshooting a no fan start problem (Cooling coil would freeze up). I swapped in the Zenith cap to replace a 4uF cap, but the problem turned out to be bad solder joints at a molex connector on the system control board. I was hot, so a quick resolder and then I buttoned it up once it was going - the Zenith cap left in the unit.
