If they had a "fuzzy" moment, it could well be dirty pots on the level controls. Work them back and forth a bit, that may clean them up enough for now. You can use contact cleaner too, just be careful with it as it can dissolve some plastics.

I’ve cleaned them with contact cleaner and all is well .

You might be surprised by those.

What, surprised how bad they are?

I’m thinking of advertising these , they must be £200 ?

£100 maybe £150 on a very good day.

Switch cleaning lubricant is what you need for cleaning pots i.e Super Servisol 10. Swich cleaner is for contacts and regular use on pots can/will make the problem worse by in effect "drying out" the carbon track of the control making it brittle.

I've never seen carbon track pots in speakers and can't imagine anybody using them as the power handling of wirewound items is needed. And wirewound should be fine with switchcleaner.

I used wd40 contact cleaner which I’ve used for years , so far without issues as far as I’m aware .
Anyway I’ve replaced the caps and the speakers are now perfect, AND surprisingly good , not worth selling for what I’d get for them , I also have some excellent b&w P6 speakers which I’m getting silly offers .
