Ok. I looked back on others previous posts. You are right I think I read some information wrong. I think I got that mixed up with low plate voltage .
The fly cage gets quite warm after being on for about an hour. 122 degrees roughly with my thermal laser thermometer. Of course there is quite a bit of heat that is generated with the HV tube as well. I'm thinking about installing a fan on the cage and drill some holes. I did this on a Magnavox U66 color chassis a few years back. I adjusted it for the lowest current I could achieve on that.
Still like to know what the cathode current should be on the CTC39 and where the efficiency coil is located. honestly I cannot find it anywhere.
I found a few caps with high esr in the vertical circuit that was contributing to the linearity issue, and too much vertical height with the pot turned down all the way. Also noticed green smear on images with red. Replaced a 47kohm resistor in the chroma section that reag 58kohm. Perfect now.
Impressive picture quality I have to say. actually color representation with red are better than the Trinitron behind it, which puts out an orangey red.
It is after I completely Gray scaled the picture it brought up the drives and screens to where I believe they should be, keeping the screens very low. Also had to bring down the brightness limiter. I'm not sure if that was factory or if somebody cranked it up but it sure was extremely bright and the way I like to see a good set up is when you turn the brightness all the way down you can barely make out anything on the screen.
Speaking of picture quality, is this a black matrix CRT?
