Yes, in these scenarios, its nice having the "good working chassis" to compare voltages. Unfortunately, I gave the other CTC-5 I had to friend and I know the brightness circuit was working properly on that one too. This was actually a problem before I recapped the set, so capacitors are basically eliminated as a cause at this point. I used nothing but the best in the recap (spragues) and I tested them for capacitance and leakage prior installation as reassurance. If I remember correctly (not at home at the moment) the brightness did not go away after pulling the 12BY7 video output. That should be a give away that the problem is elsewhere. I'll find it...eventually.
