My "New" CT-100 restoration

[dtvmcdonald]

Last night I tried to receive our actual OTA real NTSC Ch. 39 and
failed. I also failed to find a radiated local oscillator signal at UHF with a
spectrum analyzer, though I see it at VHF. I should add that the signal
is weak, but works OK on other sets because there is a 16 dB gain
0.5 dB NF preamp. Could this be a weak oscillator tube? It tests excellent.

Are all of these CT-100s actually supposed to get UHF, or only
some of them?

Could bad blooming be due to use of a 1X2A rather than 1X2B? I forget
what I found in our old stock ... it tests good offscale.
