CT-100 works! (but the zener mod didn't...)

[David Roper]

Thanks to Steve K, B8003192 has joined the still-too-short list of operational CT-100s. The 15G has a weak red gun, but for some reason these phone pics make it seem much moreso than it looks in person. Despite appearances, the green gun is only marginally stronger than the red one! Fortunately, there is plenty of brightness to spare. I haven't yet attempted adjustment for color balance--or in fact any of the setup procedures whatsoever. What you see is just from raw futzing after re-installing the chassis.

I have a spare chassis which provided a few 6AN8s and a vertical centering pot. Little else other than caps and inductors was needed. This set retains its original flyback and vertical convergence transformer, not to mention the shouldered HOT, which is an awesome thing for a color TV set to have.

I'm at the moment unable to share video, which is a shame because I can't wait to show how rock-solid the picture is with even the most extreme rapid changes in content. The regulation is unbothered and the focus constant. The last bit is important, as I had originally intended for this set to have the focus modification that Tom Albrecht invented for his own set. Unfortunately, Steve K reported that once implemented, the focus pot no longer worked. He speculated the reason might have something to do with Tom's set using a tripler vs. a flyback. I'm curious if anybody else tried that mod and what the result was.
