Possible delay line problem?

You should consider that in anyway the delay line must have a very low resistance between its ends and an infinite resistance respect the ground. Of course these measures must be done disconnecting its terminals from the circuit.

Sorry I’ve not been on the forum lately. In September ‘13 sent the chassis to a shop in Ohio specializing in restoration of these sets for a full factory spec alignment. They did an excellent job but after getting it installed last fall it is still slightly noticeable. Running the video through “stabilizer” before the modulator makes an improvement if still slightly noticeable so I decided I was being too critical of a 54 year old set. At normal viewing distance you have to look hard to see it so decided to give it and myself a break and just enjoy the set. But don’t think for a minute that I wouldn’t yank the chassis if I could find an NOS delay line to compare performance with.

It was during the re-install and set up that I noticed an occasionally vertical roll associated with a slight arc noise in the picture (another thread exists about that). After exhaustive testing (and driving myself crazy) it has been localized as internal to the CRT. Fortunately the set makes a beautiful picture with plenty of quality long before the brightness setting gets high enough to cause it to arc. The CRT tests fine with well over 100% emission on each gun and excellent tracking. It was a new tube date coded for ’61 instead of a rebuilt CRT.

As soon as I get time I have 3 B-T modulators set for our original locals 3,9 and 12 so I can use the set with rabbit ears the way TV is supposed to b viewed. We have Antenna TV and Me TV over the air locally so these will be two sources as well as a computer I’m configuring for use as a video server to program what I want. After all, I can’t show this set to a 16 year old without letting them have a go at using the remote control. The first thing they notice is the weight of the remote and then the sound of the tuning drive motor and most of them say “NO WAY”. That makes it all worthwhile for me. I’ve attached a photo of the set. Once I get the screens set up I’ll post a few screen shots.

Thanks guys for all your help and suggestion on this issue as well as the arcing thread. You guys are the best.
