Nice. Did you get the semiconductor kit in the clear plastic case with the zenith name printed on it? I've got one of those too. The infamous 121-587. Does your kit also have any 212-72 convergence rectifiers? Just curious, don't need one, but they fail alot too. I think the 587 is the most failed transistor in the solid state zeniths. They've been using that since the '68 models. When I see a weird video problem, thats the clulprit almost every time. Did you ever get a sencore super cricket transistor tester? Gotta have one of those. Nothing beats sencore test equipment when working on the old sets.
