By mentioning the 3.58 oscillator tube, do you mean the "Chroma Reference Oscillator? That is the only color related tube that I see that is called an oscillator. The rest seem to be amplifiers and demodulators. I will have to look for a sub, but I don't have a "known good". I will get back to the issue with the horizontal efficiency coil with what seems to be a broken backbone or housing. In short, I would think that it should be rigid, but I can grab the coiled end and it wobbles around separating the windings a bit.
