CTC-5 Update
From Mike,
Greetings Marshall. We are in the homestretch with this one. Still some HUE shift but that might be my JIG CRT. Replacing the Burst Transformer helped a lot but still some shift of about a 5 to 10 minute warmup. I will be connecting this chassis to my set 21AXP22 crt within the next 2 days. I hope to get a better idea of its performance from that. I hope the Hue shift goes away with that test. I have installed 2 brand new tubes in the sweep circuit even though the ones in the chassis seemed to be working OK. Those tubes are the Horizontal output and damper tubes. 6CB5 and 6AU4. I did this due to their age. I will keep the old ones for test purposes since they still work properly. I feel better knowing that those tubes in the set are new. The yoke clamping bolts were missing so I had to make new ones. They are unobtainable. I was able to contstruct them from some 10-32 threaded rod, some small nuts and wing nuts. J-B Weld epoxy played a big role in the process. If all goes well I plan on delivery of this by the end of this month. I will figure out timing and let you know soon. I stll have to find or make a new cover for the deflection yoke since it has deteriorated over the years. I have a plan in place for that. As for the back cover, I will be finishing that at your house and I will bring all of the materials and tooling to do so. The measurements are still a bit unclear so I think that doing it there is best. I have found the proper chassis bolts so that is no longer an issue. I think the “pencil box” screws are missing also so I will be bringing those too.
Pix 1 is what the original yoke clamp bolts look like. I took this one from my set for the photo
Pix 2 is the 2 that I have fabricated for your set.
See you soon.
Cheers, Mike.
