Deoxit Convergence Pots?

[Electronic M]

If the donor coil is the same and the only damage to the original is the adjustment slug and it's not stuck you can just spin the slugs out of both, blow any debris out of the one in the set, and spin the new slug into the new coil... I've done this more than once.

It's an NOS replacement. I got just about every pot and inductor on the board, but never got around to replacing any. So if the replacement is factory, and NOS, should I use it or just the slug?

Either approach should be workable. I'd use just the slug. Changing just the slug is easier, minimizes the chance of wiring errors or damaging the original or replacement coil and if you ever accidentally damage the coil form of the original (or the plastic degrades and fails... which happens sometimes on 60s Zeniths with that style coil form) you still have the replacement coil to fall back on.

It's your set so the approach you take is your call.

Slug change it is!

Since I just learned that multiple posts on same TV isn't the best approach, I'm going to post this here because it's the closest thread to my next question.

I was searching the internet for all the info I could find on my model (Avante SE2564X) and came across something from another forum (Zeno was helping them). In one of the pics posted, I noticed the routing of the convergence board wiring was routed much differently than mine. It got me thinking that maybe mine is wrong? I'll post the images and maybe someone will be able to chime in. Mine is tied together with a yellow tie. Not sure what it's called, but it seems to be a version before our standard zip ties. Maybe it was changed from factory routing.

Anyway, let me know what you think.

Well I feel like a complete idiot. Ignore everything I asked in this thread. I really should have gone over old threads before starting this and also looked over the convergence board. It's been almost 13 years since my initial work on the set and I completely forgot I had tackled most of these already. I replaced all three inductors and cleaned all other pots.

They only thing I didn't do is replace the pots that might be causing the right side red and green not adjusting to match the blue. I know have those pots and will replace Monday. The only thing I needs is some tips on how to unsolder them. The leads are down into little metal "buckets" and then filled with solder. It's the same inside the set on all the underside components. I tried holding my iron on the metal "bucket", but it never got hot enough to melt the large blob of solder. If I could find a long, thin tip I might be able to get down into it. I don't know what they used at the factory, but I'm assuming it was something that surrounded the little "bucket."

Attaching a small pic of what I'm referring to. In it you can see how the leads are set into solder inside the inserts. You can also see one filled, but nothing in it.
