Correct..Servisol is the way to go. But if the track is worn or
damaged then replacement is the only long term solution.

But someone must have manufactured the track in the first place, so it
should not be beyond the bounds of possibility for us to attempt such.

Well it's going to very difficult to find and if you do it'll be very
expensive to buy an OEM part.

No, I meant to try to manufacture such a part ourselves.

I have the maintenance manual for it plus the ATU and the 2m converter.

WD40 is not a good choice, though some may have used it in emergencies.

IT depends on the potentiometer. A lot of the old ones could be pried
open, little tabs at the front. But there are also fancier ones that
are sealed up in plastic casing, I'm not sure if those can be opened,
though hopefully some of the dirt problem is fixed. Maybe drilling a
tiny hole (like for component leads on a circuit board) and then
dripping some cleaner in would work?

I remember some 40+ years ago when I part-timed for a CB shop. A guy
brought in a radio with a broken squelch control. His son tried to fix
it with WD-40 or something similar.

Of course, it didn't work (taking the control apart, the wiper was
broken).

WD40's good - but not good enough to mend broken wipers!

Charged him $15 for the repair (remember this was a long time
ago!) and $25 to clean up the oil all over the case.

I doubt his son tried that one again!

On the occasions when I've used WD40 on pots, fan bearings etc, it
hasn't caused any subsequent problems. But, of course, you must use it
vary sparingly.

me too I also ... +1

"proper" contact cleaner works better and doesn't pick up contaminants
like WD40 does.

But, of course, you must use it
vary sparingly.

Indeed, and at the force it comes out of the can, that can be tricky.
Spraying it into a small snootiness and using the tip of a screwdriver
to transfer it works. But for pots, switches, etc., it's still better
to use contact cleaner made for the job.


Exactly. I would never use WD40 on an electrical/electronic device.

I would and do all the time ......
