Scratchy volume control.

[Peter Jason]

I have one of these......

https://i.ytimg.com/vi/1VHkWsb9MY0/maxresdefault.jpg


The volume control wheel (at the side) has lost
all fine-tuning capability, and makes appalling
noises when operated as it jumps at random from
high to low volume.

Is there a fix; is it a loose connection, dust or
grit in the works? Should I just flush it out.

Otherwise the radio works well.

There are a number of good professional spray products for fixing bad
volume controls. I use M G Products Nu-Trol and my customers are happy
with the results. Use a spray that is specifically for volume controls
as the composition of the sprays varies from ones for switches, etc..

Do NOT use WD-40!!!!!(and on!!! and on!!!)

Sometimes all one need to is twiddle the control back & forth a dozen or 2 times. Sometimes it also needs some cleaner sprayed into the pot. Sometimes that doesn't fix it & it needs its terminals resoldering.

and rarely the track is worn out.

 

[Look165]

Generallly, it comes from a bas contact between the cursor aand the
resistive track (dust or oxyde).
It can also come from a miscontact between this track and the connecting
pad or a "dry solder".
First step : re-solder everything.
Second step : use some KF or equivalent in large quantity inside
(through the opening of the leads).

Peter-

You have a number of good suggestions above.

While you in the radio, check to see if there is a capacitor coupling to
the volume control. It is possible that a leaky coupling capacitor is
causing a DC current to flow in the volume control. Such a current can
cause any "scratchiness" to be made worse.

I feel that the horrors of WD40 are greatly exaggerated. Since I lost my
tube of 'the real thing' (about 40 years ago) I've occasionally used
WD40 as a switch and volume control cleaner - and I've never had a
problem with it.

Would finely-powdered graphite work in this case.
Like the type used for door locks?

Graphite is a rather good conductor. Not an ideal material for the purpose.

No.
1. It does not remove the gunk causing bad contact
2. It tends to short the resistance in use
3. It tends to create a short from track to case, which sometimes would be a problem.

It was sometimes used in the 1940s on pot tracks that had worn away, but that is not likely to be the problem, and certainly was not used by pouring powder in, and was at best a temporary bodge.

Imagine if our Tourette's Twit from Australia were to engage in its little fits face-to-face with its neighbors, acquaintances and customers?

Dubious that it would still be alive, much less at liberty.

I have often thought about asking a friend of mine who travels throughout the Down Under on a regular basis to see if he can get a picture of Mr. Allison - just for giggles. He is an ordained minister, so no threat.
