Rca Ctc-11

Having it take awhile to come up to full brightness is almost always a condition of a tired CRT. It can also be a weak video output tube or failing power supply capacitor. Look for ripple in the picture (a weave, almost like the picture is "breathing") That is a good indicator of failing power supply caps.

The 11s really do put out a good picture. I have two of them. It is OK to see a little melted wax near the flyback over the life of the set. Just check to make sure the flyback isn't runing hot. Check the cathode current of the horizontal output tube. If its too high, the flyback will overheat.

If you don't have test instruments the best test is to cold start the set at room temperature and run it for 5 minutes. Then shut down, unplug, open the HV cage and feel the body of the flyback. If its cold or at room temperature then all is well. If its warm or hot then you need to check the horizontal output tube and readjust the Ho cathode current.
