This is awesome, it's been a while but remember this thread started out as a 15GP22 for sale from a set that was being parted out, what a shame that would have been!
It looks incredible! |

Nick,
Crosshatch looks nice; horizontal linearity at the left side of the screen can be a pain sometimes. No horizontal overdrive visible; did you have to make some alterations or did it go away? Pete |

Wow a hell of a find. Good luck. Want to see it when it's all done.

Umm, it is done... Quote:
Incidentally, if anyone in the area would like to stop by and see my small collection, I'm game. Just shoot me a PM, and we'll set something up. Quote:
I had to change the value of R176 (Sams), it was 47k now it's 22k. Making that change got me to where the drive control actually has some range instead of being at it's extreme CCW position. The real cause of the issue is the negative voltage coming from the power supply is a bit off for some reason; it reads -24 or so when in Sams it calls for a full -30. Still don't know why it's low, the only thing that could cause it is a iffy choke or 2R191 being low in value. They both check out within tolerances, so I made the drive mod. Also, horizontal cathode current is reading nice and low post-mod. I think when I first read it, I got 168ma or something? It's lower now, checking in at a solid and steady 140ma. So I trust the mod isn't having any negative impact on the performance of the horizontal output stage. <shrugs>

Excellent work. It's fun to see a CT-100 looking so good.
