The first in the bunch to work
This is the first set out of the ones we picked up in Seattle. It is a CTC-16XL from 1966. I removed the cataracts and reinstalled the CRT and cleaned out the cabinet. Not too dirty. The chassis was very clean. It needed several tubes. All the caps check good. There was some bad solder so I went over all the boards carefully and re-soldered anything that looked flaky plus all the grounds. I cleaned all the controls and tuner. I was rewarded with a raster and a very decent picture. It will need a convergence touch up. I checked the cathode current and its about 208ma, I made a permanent jumper for convenience on a small terminal strip. I made some minor adjustments to the vertical height, horizontal centering and grayscale. I set the HV to 24KV as per Sams. The electrolytics stay cool even after several hours of running. This is a very easy chassis to work on. Much easier than the CTC-9. here are some pics
