My "New" CT-100 restoration

[dtvmcdonald]

Two more questions! When the picture goes absolutely totally blurry on an
all-white screen, is it the 19,500 volt HV or the focus voltage, or both,
that collapses? I suppose I could measure them, but with the chassis
in the set and turned on, I'm afraid of accidents.

I'm missing my horizontal and vertical hold knobs. The rest look
rather generic ... where do I get matching ones?

No knobs, these are just knurled shafts.

REALLY? I find that hard to believe! These are user controls.

McVoy did, however, say "all knobs"

I am about 99% sure that the horiz and vertical shafts were never fitted with knobs. If anybody here can prove otherwise, that would be welcomed information! The CTC-4 also has a similar concentric knurled shaft configuration in the pencil box, but in that case it is for vertical and tone controls.

My CT-100 has just the knurled shafts, and this diagram seems to show them without knobs.

Well, Steve then must have been right ... it was all there.

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

Do you have the proper strips installed for the channel?
