CTC-4 Director 21

[DavGoodlin]

What generator setup would you be using for an alignment?

I have two very original and crispy CTC16 chassis' I must repair for a combo owner, so I will be looking at this issue for sure.

Usually the adjacent sound reject adjustment (before the first IF) and sound reject (at the third IF stages need to be dialed in first.
Not sure of a CTC4 swizzy, but start there - it could be all you need to tweak.

I can do alignments Dave, I have a full setup here and I'm only a state away from you. Just did a CTC-9 not long ago.

I'm not clear on the restoration status of this set. Did the previous owner do some minimal "make it work" repair years ago? Did he do a full restoration? Something in between?

If the original electrolytics have not been replaced -- or at least checked! -- I would not feel safe running this set for prolonged periods.

Forget alignment for the moment. TVs don't un-align themselves by sitting around. Install a full set of tube shields and see if they help.

The previous owner was a TV repairman. I was told he would fix the set if anything was acting up with it. He never did a full restoration, he just kept the set alive. I can see some wax caps that are still on the boards and in other places visible on the top side of the chassis.

Putting shields on the tubes helped a whole lot. There is still some interference with the color picture but not the B&W picture. Colors are off in some settings and text is difficult to make out. I used my CTC-7 for a picture comparison (hope you dont mind me riding your coattails with that panther lamp Phil! ). Please ignore the moire effect on the 4 that isnt visible under normal vision nor is it that distorted looking. There is still some beat frequency but that's about it for interference.
