Philco round screen - CL

I think that is a CTC-15 clone. The only lytics are in the power supply, and I believe a few in the vertical. The reset Are mylar film, and rarely ever fail.

Looks like the green gun is weak, and you are missing most of your Y (video) signal. If your lucky and the CRT still has good emission, all you may have to do is replace the small amount of lytics, some tubes, perform greyscale and convergence.

After you change out the caps and tubes and get it running well, make sure to check the Ho cathode current. Anything more than 210ma and you run the risk of cooking you flyback.

You may want to consider This if your CRT is weak. just make sure you instruct the seller how to properly pack it.

Thanks for the info Jordan. I did some more tweaking and changed out a couple tubes and was able to improve it quite a bit. The crt has good emission on all 3 so I'll let someone else go after that ebay auction.

Yea you're right, it's a clone. One thing seems odd though, there isn't a single philco tube in the entire chassis. Most of them are magnavox, the rest are rca, ge, and raytheon. I would assume that means this set has pretty high hours.

Are the convergence adjustments going to be a nightmare on this set like they are on my ctc-31?

Here's some more pics of my progress:
