not that far off.you can tweak some more and maybe move purity rings very slightly to pull it a little closer.the blue horizontal could move a little more north.i know how this is.you want it perfect.tweak it some more just in those areas but it looks much better than it did and is close enough to enjoy.great progress.set looks good.now some screen shots,please?

Like I said, I'll wait until the new coil and pot arrive. Until then I'm going to let the convergence be and enjoy what I have for the moment.

when you were checking those pots remember some of them may not test right in circuit. You would have to look at the schematic to see if they are isolated.
sometimes you have to comprimise the dynamic convergence, get one side perfect and the other is off a lot, in that case you shoot for the same defect on both sides. How much is normal and how much is a defect in a part can be hard to say. Just remember the idea behind dynamic convergence is to get the lines straight if thats done then it should be pretty close when the static is right on. there was a post in the early color where a member (6GH8 cowboy IIRC) was having some convergence issues and it was bad caps. If I was have problems I would break out the scope and see if I could see the needed waveforms going to the coils. if they are there then it clear the parts as an issue so just focus on correct setup. Make sure you have all the neck parts in the correct position. Last edited by DaveWM; 08-27-2013 at 12:54 PM. |

The one pot that tested oddly also had a click that sounded like a wire might have come unwound or something and was clicking as the wiper pushed it over. You could even feel it in your fingers. The coil is a given as it's seized. I'm pretty certain you can't lube the core of them. They seem pretty porous and I'm sure it would ruin the core.

smoothly working pots is a def plus. the zenith coils (if they are the plastic ones) can be a real PITA as the plastic crystalizes.

Yeah, I noticed the pots and coils run around 100 degrees and that has to take it's toll on the plastic coils.
