1964 zenith hv & ho current issues

[Tubejunke]

OK, it seems that once again VK members have come to the rescue. This is the best site and group of people that I know of! A member found several old chassis and should be having a socket and sub-chassis sent to me soon. I will post as to what (hopeful) improvements correcting the burnt socket and resistor bring in regards to cooling down my flyback and reducing HO cathode current.

I am almost certain that this set was working with the single 1 watt resistor that mounts on the socket burned in two. I am not certain what the open circuit would cause or if operation would be possible. I am thinking that the open resistor would stop HV from making it to the regulator. There were never any obvious regulation problems; just the hissing that couldn't be seen in a dark room and sometimes distortion in the raster that went with the hissing. I just know that there would have been a heck of a smell and the only smoke ever seen or smelled was WAY before this burned socket became an issue. I am hoping that finding and fixing this culprit will prove to be a great improvement to the set as far as the HO cathode current and fly temp.
