Another CTC Surfaces In WI

[droptop]

Kevin,
Great score- and you had help loading. It doesn’t get any better than that. There is quite a difference in the veneer pattern between the two although the color is the same. I’m just glad it found a new home.

The set I have appears to be in similar condition to yours- just light scuffs etc from 50 years of use. We both got lucky in finding the sets in such good shape fresh out of the house. I haven’t powered mine up yet as I like to change out the electrolytics to keep stress off the power transformer.

The CYP in my set checks out great. Hopefully I’ll get time to work on it soon. Is your safety glass clear or tinted? Mine appears tinted the same as on my CTC 7 Grenoble. Did they come both ways?

Keep us posted on your set and progress.

Rick,

I thought it was clear, but it's really hard to say for sure without taking it off. And I'm not even sure how to go about doing that.

I did the bad thing and turned the set on without replacing the electrolytic caps. I slowly brought up the mains voltage while monitoring both the AC input and the HOT cathode current. I also have a 3 amp fuse in my variac. All seemed well, and I had a raster, but I couldn't get any video through the tuner. The pictures below are with the B&K 1077B's signal being directly injected into the IF though that phono plug that normally goes into the tuner. And there's no audio either. At least I know the HV and sweep circuits are working pretty decent. And the big filter caps stayed cool after an hour or so of this goofing around.

So now I need to figure out how the HV wire comes off that 21CYP22A. You certainly don’t take the CRT out to disconnect it? The HV wire disappears behind the CRT front clamp/cover.

wow, that has great color and lineairity.

They are shockingly colorful. I watched a 60's RCA color set as a child, but I had no recollection of how well these worked until a couple of weeks ago. That was when I fired the CTC11 up.
