UPDATE, APRIL 9, 2019, DAY 252
WE HAVE VIDEO! FIRST IMAGES.
From Mike: “Hi Marshall. The jigging process went as planned. The focus voltage is missing and I’m not sure why just yet. I ran out of time tonight. There is a LOT of GOOD NEWS though. The image is there. It is in good vertical and horizontal lock so the sync circuits are working and the chassis is actually sweeping a raster. With no focus voltage, the images are very blurry. I will sort that out when I return from my vacation. The other good news, is that the convergence voltage *(on the wire that is not connected to anything),* is swinging from 5 KV to 8 KV with the convergence pot. That means that I hit the numbers quite close with my calculations on the first pass. Very, very good news in my book. I am pleased with the results tonight even though there is an issue with the focus voltage that I did not expect. Also, I have not installed any purity correction yet and there is no static convergence installed yet. And, the images here are showing a “ring” in the foreground. That is the chassis portion that normally carries the deflection yoke. And there is no way to keep it out of the picture. All I wanted to do tonight is display an image. So here they are. Likely the first images that this set has displayed in many years. We are winning.
Regards, Mike”
** The wire from the convergence is ready to connect when I replace the crt socket which will happen after the jigging and before I install the 15G, and the pot is installed as per the picture I sent several weeks ago. And this part is still considered experimental until I find the correct voltage value for the 15G. The convergence wire will remain connected to nothing at this time, but will serve as a test point for voltage adjustment by the new convergence pot. When I am satisfied with the voltage numbers then I will do finish work around the pot and install a barrier insulation in the cage.**
Author: On day 252 of this restoration, we have our first images, albeit, very blurry. I feel good about this and it’s definitely a milestone in the restoration.
