I've had three types of sets that use a ferroresonant power supply with a 3.5uF oil-filled cap; Zenith of course, Sylvania and Electrohome. When I wanted to replace the run cap in the latter I was told I couldn't use a 4uF cap (I ended up getting a NOS 3.5 from a member who is no longer active here). Now I'm wondering if 3.5uF was a common value for run caps when these sets were made and 4uF was practically non-existent, basically the opposite of what we have today. Can someone clear this up for me?
By the way, nice score on the TV. The unusual feature set is pretty cool.
