Sync or not you first need to get it to the point where you can tune the osc to not have many barber Pole lines but what looks like continuous to tint drift... once you get that if there's any life in the chroma sync it should be able to lock.

but i'm not sure I'm getting anything for it to lock onto.
I'm seeing nothing at the bandpass coil even wit the tube removed ( same tube has the color killer )
there are no pules at all v23 chroma phase detect.

what should i be seeing at point 80 ( v17 removed )? I'm seeing nothing but noise, no video, the overpowering horz pulse that was there is gone, but, no video, so i suspect there is an error someplace that i have not found yet .
