The caps to be wary of would be PS lytics, sweep/deflection stage caps (where the unobtainium lurks), and since it is not working quite right RF/IF/color stage caps.

Subbed the two 6CL6's. Powered it up slowly. The colors are spot on now and I now have a nice picture. Still a bit of interference and small letters are hard to read. Needs some dynamic convergence, static conv is good. Set isnt drawing a lot of current. Only about 2.5 amps according to the PR57. Operating at a full 375 watts the set would draw 3.2 amps but it isnt even near that at 115 volts. I do still plan to electronically restore this set just trying to get a base-line on what Im dealing with. Ignore the Moire effects. The blue screen is turned up a bit too high in these photos.

I think you want to optimize focus, increase contrast, and reduce color level.

Amen to what Electronic M said.

Also, speaking as one who has served hard time grinding his teeth over dynamic convergence, I'd try all other adjustments & tweaks before you mess with that. And if you're convinced it's necessary, read the instructions carefully and perform the steps in order.

"Ahhhhh! Patrick! The screen looks like a fishbowl and I see wavy lines everywhere!"

I looks like IF strip ringing, by either a bad tube or loose connection. I hope, it's not an alignment issue.
Is the CTC4, the only RCA set, that used the 6AZ8 tube. :scratch2:
My Knight-kit R100 receiver uses two of them.

I sure hope it isnt alignment. I'll take a look

Starting to think this may need an audio alignment. I can fine tune in a clear color picture, but the sound isnt there just the loud buzz of the modulation. When i turn the fine tuning knob to receive sound, the picture gets a lot of interference and the swirly lines show up. In other words the audio is not at the same tuning position as the clear picture signal. I suspect an audio alignment may be necessary.

Hope it's not the same issue mine has, the audio went totally kaput on it one day and I think the IF can has an open winding or something. I can twiddle any slug I want, all it does is sound like a radio not tuned to any station. Gotta dig back into that thing at some point.

Might want to check that it don't have silver mica disease.

Unfortunately this problem sounds like a bad main IF alignment, or else a fault
in an IF can, after fixing of which an alignment is needed.

Despite what some people say, every single postwar set I have has been
seriously out of alignment, even if it "worked OK". The picture quality and picture-sound tuning spot coincidence has been improved by either a tweek or
full alignment. If you tweek, only tweek one adjustment and return to original if
it does not completely fix the problem ... hoping that one big tweek and
one little one will 100% fix it is well on the road to Hell.

My TRK-12 was spot, perfect, on. If I could feed its video into a CT-100 it would produce a perfect color picture. The TT5, pretty much per spec, but a one-coil
tweek made it look better.

Is there any fine-tuning spot where the audio is loud and clear? (That would rule out silver mica disease and show that your audio section is basically OK.) On some sets where the audio has separately drifted away from the video, you can "walk" the audio alignment back into step with the video by carefully tweaking the audio adjusters while watching and listening. This is lower-risk than attempting a full-dress alignment of video and audio IFs.

No matter where i fine tune the audio its always got that horrible overmodulating hum (not filter cap hum). It gets louder as I turn the knob to the right.

Now that the picture loads....

I think this NEEDS to become a VK web meme! :D

Just put in an order for the filter caps. Hope to get started this weekend! :D
