CT-100 performance mods

[ChrisW6ATV]

Thanks for the notes and picture, Nick. I had seen notes of these differences before (from Pete Deksnis if I remember right), and I am about to repair my CT-100's HV cage, so this is an ideal time to go ahead and make the updates to my set before I power it up on my test jig.

Through the magic of the Wayback site, web.archive.org, some of my now-defunct site (thanks ATT) is viewable. Here's what I believe you were referring to Chris:

It covers CTC2 production changes to the vertical circuit and the boost B+. [Since photos did not get saved here are photos of the pages, which incidentally were saved by the late Len Dole and given to me by Phil Nelson.]

The reference-designation links do not work, but were only photos of the noted component.

Typically, connecting a vertical sweep oscillator to boost B+ made its sawtooth waveform more linear, as it increased the amplitude of the oscillator waveform and therefore the small portion of the exponential wave used to form the sawtooth would better approach a straight line.
