CT100 S/N B8002567 Lives!
I thought I'd install a thread here about the CT100 I picked up from the ETF
two weeks ago. The restoration log thread is in the technical forum. This morning was the big one! I installed the yoke and purity coil on the CRT, and put the chassis in the cabinet, and attached wires. At 8:10 this morning I turned it on. No nothing. I hooked my scope up to the set attached to the red CRT drive ... noise only. I thought maybe it needed a signal, so I turned on my RF generation system. Still no nothing. I tried brightness , contrast, and screens, no nothing. I tuned around and didn't find a TV signal ... but a bit of noise appeared on the scope and a bit of blue light on the TV! A quick change in AGC generated more blue. First picture, 8:19 AM. Still no signal on scope. http://www.videokarma.org/attachment...1&d=1406738069 My Sony Watchman showed no signal either: the video to the modulator was plugged into the DVD player, not the STB. Fixing that resulted in a picture on the Sony. Tuning various channels on the CT100 found Ch. 10 on Ch. 13 (I had set the knob wrong). This was at 8:27. http://www.videokarma.org/attachment...1&d=1406738069 The progress from there is shown in the pictures below, just adjusting the full set of controls available on the front and the focus. http://www.videokarma.org/attachment...1&d=1406738474 The vertical hold was off. http://www.videokarma.org/attachment...1&d=1406738474 The fine tuning was off. http://www.videokarma.org/attachment...1&d=1406738474 The images being sent from the station were rather, ah, odd ... the 55 inch LCD TV looked only a little less strange. Yes, it was that green. http://www.videokarma.org/attachment...1&d=1406738474 All it took to get a good picture was a teeny adjust of Hue. Oh yes... I forgot to make sure the audio was working before installing the chassis in the cabinet ... its dead, so I'll eventually have to remove the chassis and fix it. That's rapid progress. It'll probably slow down a lot from here. But that last picture was actually watchable. Doug McDonald Last edited by dtvmcdonald; 07-30-2014 at 01:09 PM.

What fun to see the picture shape up by stages. You seem to have plenty of R, G, and B -- now, to get them in all the right places
 Nice work. Phil Nelson Phil's Old Radios http://antiqueradio.org/index.html Last edited by Phil Nelson; 07-30-2014 at 02:53 PM.

Those are some really brilliant colors. Kind of magical seeing on of those come back to life.

The brilliant colors were just adjustment to get a nice picture.
They are not real. Later tests determined that the control settings were well off normal, so something was amiss. Chassis repair needed. At this point I return to the repair/restore thread over in the forum for that. The culprit has been found.

Great success! THANKS for posting the pics. I am always excited to see another vintage color set come back to life. Just the way I am, and have been since I "discovered" color TV in the 50s!
 All the best for you and your CT-100!! Kevin

That looks very nice. I have to be honest that I never knew about the CT-100 until I started hanging out here and over on ARF. I doubt that I will be able to own a CT-100 because they are so rare and expensive ... but it would be nice.
As a kid, I was very impressed when they came out with rectangular color kinescopes. But as many, as I age (66 now) I have come to appreciate "antiques" much more than before. I have a CTC-9 in queue. Again: Nice work! Thanks for taking the time to share! Hope we see more! Congratulations, especially on the CRT!!!

Thank you for preserving history step by step.
I'm also relieved I dint need to be the one to do it - the pressure would be too much!
