Possible delay line problem?

[droptop]

Thanks for all the input. I didn’t get a screen shot before dismantling the set to clean a noisy pot so I can’t post one at the moment. The fine tuning doesn’t affect this symptom at all.

I’ve checked the peaking coils and all are good except L17 (series peaking coil) feeding the video output tube grid which is open. Specs are 11 ohm coil at 250 microhenries wound on an 8200 ohm resistor.

I’m not familiar with their exact function but is it possible to rewind these or do I stand a better chance of finding a good replacement?
