CTC-9 restauration.

The coil needed some adjustment but very little. I tuned it before but without shorting the reactance tube. Still a little "lazy" but much better. Checked a few elements around it and they are pretty much within specs. Could be more than one that drifted over the years. Tempted to leave it like that, do not want to make it worse by fiddling too much. Thanks for your help.

Tweeked the coil according to the advice and it is a lot better. Still a little lazy but locks a few seconds after the raster arrives. Checked a few elements around the area but all seem to be rather OK. I guess more than one drifted away. Do not want to make it worse by fiddling with it. Thanks all for your advice.

I guess it became porous over the years. The eff coil was replaced and the current is now 190 mA. It takes 2-3 minutes for the color to sync when powered up with 110v. All tubes checked OK. When the set is poweredup with 120, the color appears immediately. could live with it that way if it does not degrade any further.
Thanks for all your tips.

You did a really nice job on your set. awesome color.

Just for the record, I'd like to compliment bgadow's detective work in finding the too-long replacement cage screw at long distance.

That's the kind of real-life tip that you can't learn from a book -- and why forums such as this are invaluable for folks (like me) who don't have mentors peeking over their shoulders.

Phil-glad you could learn from one of my mistakes!
