BTW: line voltage affects these a good bit. There are usually 2 line voltage taps on the transformer primary on most RCAs having it on the best tap for your line voltage or even runing the set off a variac set for balance between normal picture and minimum H output cathode current is not a bad thing to do.
Couple of other things you can do are to make a ventilation hole in the HV cage and mount a small fan to draw warm air out to cool the flyback. Also on the CTC-16 I serviced for a dead beat (guy still owes me money) that used to be active here. He wanted me to remove the rubber tire on the HV winding and replace it with Silicone based on this video: https://www.youtube.com/watch?v=BUnPkymnxUw which I sucessfully did for him. Apparently the rubber beraks down and becomes conductive sometimes as it ages. |
I will keep on eye on the fuses and the power draw and report back how well it goes.
Thats good to know about these sets. I think it may be worth it even if my line voltage isn't as bad it still would be better from what I've taken notice here the last few days.
I really like the idea to ventilate the flyback cage, I've been thinking about doing that as well. I really would like to do what I can to keep the flyback good. I can't believe that they put a tube in a metal box with the flyback, its gotta get pretty hot in there. I did notice though that the tube says it has X-ray radiation and perhaps maybe that's why they have it in a cage. I wonder if there would be X-ray leakage with drilling in some holes at the top that one would be concerned about
Is there any signs when the rubber becomes conductive and becomes a problem? I may give it a shot in the future and try to do that as well. Really sucks someone didn't pay you for your work, that's the worst.
