After a month of normal operation the set developed a red *Purity* spot at the top right corner of the picture. Installed a small magnet on the picture tube to correct the problem. *Purity*. Intermittently a ""Bull's Eye"" impurity pattern would develop. Traced the fault to an intermittent connector connected to the degaussing coils. Repairing the connector restored normal operation. *Purity int* Problem described as an intermittent bulls-eye type of purity. Also had arcing and a band of distortion going throuh the picture. The pins on the degausser plug were very loose and it caused the CRT to be magnetized. Could manually degauss the tube. Reformed the pin on the degausser.

(circles). Going on a service call for the second time, CTC169 chassis. The degaussing circuit is working as it should. After a month the set develops impurity with perfect circles in picture (looks like a bulls eye pattern of different colors). I can manually remove with degaussing coil. I can remember some else with this problem but can't find the information. thanks for you help, Bruce.
