In this article for antique 1955 to 57 Zenith tv set, a guy says to replace the selenium rectifiers in the tv. What is wrong with them, or do they go bad from age? I remember working on a lot of the old tube stuff that had the selenium rectifiers, and I always thought they were an improvement over tube rectifiers.
The article is here:
One other thing. I know a guy who has one of these old Zenith sets. (a little different than the one pictured on this site, but about the same age). The CRT is nearly dead, you can only see the picture in a dark room. He tested everything else, and already put on a CRT booster, so the tube is just plain worn out. He wants to find a new CRT, but dont know where to buy them (if they are even available). Do any of you know of a place that still sells replacments? I also recall hearing (years ago), that there is (was) a company that rebuilt CRTs. Anyone know anything about any of this?
Thanks
