Are these components on a PC bOard? Maybe a bad solder joint? Try bridging a resistor directly across the coil?

All point to point wired. Resistor did nothing. I think I will just get the color set up and worry about this later, maybe I'll think of something while Im doing that.

Now on to the color for now. Everything seems to be fine except for colors with magenta. As you can see the magenta bar fades off into red which I attribute to bad phasing in the G-Y(?) channel. I just am not sure how I would fix it (Phasing adjustment?).

it really would help to put a scope on the R-Y, G-Y, and B-Y outputs to see which ones are smeary. It may be the B-Y amp. If all are smeary, it may be a chroma alignment or even IF alignment problem. How is it affected by fine tuning?

Doesnt seem to be affected by fine tuning at all.

Then you can cross IF alignment off the list.

Thank god. I will have to hook up the scope tomorrow.
