Is Switch cleaner ok

[tannoy man]

Hi,I'v just taken delivery of a Radford SC24 Pre Amp in seemingly perfect order
but the Volume Control is a vertical Slider which is noisy. I'v got some Servisol
Super 10 Switch cleaner and was wondering if this would be ok?
Also the circuit boards are the vertical slide in type and I'm not sure of the
best way to clean the connectors on these?
Any help would be much appreciated thanks

Yes, your switch cleaner should be fine, both for the slider controls as well as to clean the PCB edge contacts.

Thanks Barry, I really am astonished at how good this sounds, it has not been used for Three years, delivered today plugged it in and WOW must have
a certain synergy with the STA 25.
PS, How long should I leave it before plugging it in after cleaning the Switches?

Hi Paul, you should be ok straight away fella It's a cleaner & not a conductor, the stuff used to be regularly used on TVs that were being repaired in a shop that my father managed - while they were powered up

Maybe not the best recommendation, but I think you get the idea...

If it's any consolation Paul, i used a very well known switch cleaner on some crackly carbon pots two years ago, it's still crackle free now.

Servisol is good stuff and probably the best we have found for sliders. Be a bit wary of using cleaners that contain a lubricant when cleaning sliding controls as they can leave a residue that dust particles stick to. You will often find that the crackling problems will return in a month or two as dust sticks to teh lubricant.

Servisol 10 has a lubricant I believe, but I and other engineers have used it for decades now with no issues at all.

Nice old preamp, that SC24. Only used one briefly and really got to know the ZD22 which replaced it (quite a bargain at the time).

Hi,

I've always had good results with CAIG DeoxIT faderlube on volume pots. I use regular deoxit 5% solution to clean and then faderlube. I have never had to re-clean a volume pot once treated.
