Yep. The caps are similar to motor start capacitors. Zenith used them with Ferro-resonant transformers - a great way to economically get some regulation of output voltages. It is fairly old technology, but works great when the caps are healthy. I recall replacing maybe two or three of the caps in 20+ years of servicing Zenith Duramodule sets. The caps are 3.75 or 4 microfarads, at 240 volts, IIRC, and were standard size. I was in Lebanon, TN once, and had to fix my uncles Zenith - a trip to a local hardware store was all I needed to buy the cap, as they had an air conditioner motor start (or run, don't remember now) capacitor of the same value. Be careful - AC bites!
