Thank you for the tips. I agree with and undrstand about that "SOMETHING SPECIAL" feeling that you often get from a tube doing its job. I have sat and watched a chassis work with the lights out for quite a while many times. Seems like the HO causes a lot of issues in these color sets, more so than I can say that I hear about in the black and white world, which is where I have spent most of my time. I owned several "roundie" color sets back in the 80s because in the early 80's I was a kid that would wander into the local TV shops and be fascinated by the older stuff often buried underneath newer finished repairs or other sets that the owner never came back and retrieved. I think that it sort of impressed the old TV repairmen. Several times they gave me the old color sets that I mentioned. I remember one was a remote set which I thought was a big deal being my family had just progressed to our first remote controlled color console for the living room. I was toying around with old TVs even then, but my abilities were VERY limited. I was lucky that those old color sets would play all night long, and for years with little or no repair. When something went too wrong back then I would just part a set out and find another. I could even swap color CRTs back then, but I was certainly weak on circuit repair.
This current Zenith model 5111 to me is the best thing that I could have wound up with. The metal cabinet makes it lighter and probably dissipates heat better than wood. The lines are clean and the set is about as basic as one could imagine. Mr. Muntz must have given Zenith a kudos for their simplicity!
As long as the Sylvania crt is up to par, I should be OK. The blue gun reads weaker than the other guns, but still within the "good" range of my tester.
