Volume knobs on a Creek CAS4040
Glenn Booth
knobs off a Creek 4040 amp? If so, do tell how (or
advise me against it, if you wish me an easy life).
My most reliable ever piece of audio gear seems to be
developing a noisy pot, probably on account of a) gear being
cantankerous, and b) me having said how well behaved it's
been. I paid a whole 125 quid for that just the other day...
in about 1982 I think it was. Ungrateful bloody machine.
Thanks,
Glenn.

Get some switch cleaner from Maplin, put the outlet next to any orifice in
the pot, and squirt liberally, while working the knob by hand. When the
action is smooth but silent, you are done.

This will work for a while but the only solution is replace the pot.

Must try harder with the double entendres. :-(

Tends to be a short lived cure unless you use a lubricant as well. There
are combined types available.

You could. I wouldn't dream of it.

Funny that, I raised the same question the other day in another thread.
A sales chap at Audio Excellence once told me they used it to clean
their gear, but it sounded dubious, and I've resisted trying it for
about 15 years.
Apparently it can leave a residue. That makes sense to me - stuff that
goes sticky over time doesn't mix with pots or switches, but
I can't say I've ever noticed how WD40 ages. I really must pay more
attention!
Anyway, I avoided the issue. Thanks for the replies, but a quick peek
inside the amp gave it away, and judicious use of a cotton bud and some
isopropanol has eased the problem...at least temporarily. I'm due an
upgrade in that department, though.
I still have no idea how to remove the rotary knobs. Those things are on
there good, no signs of screws inside or out, and if it's a friction
fit, it's a bloody good one. My aged Creek amp now owes me about 50p in
total.
Thanks to all who replied,
Regards,
Glenn.

It's main purpose is as a water dispersal agent for drying out wet
ignition systems. Also as a penetrating oil. And it leaves a gunge on
things when it dries out.
A can of Servisol or Electrolube cleaner/lubricant is cheap enough and
designed for the job. It's quite possible that WD40 will help a noisy pot
in an emergency, but I can't see it lasting as long as the proper stuff.

Servisol will also disperse water and will probably penetrate farther and
quicker than wd40.

I use servisol & wd40 - I would say that the difference is the proportion of
solvent to oil in the mixture, wd40 has more oil, but servisol greater
solvent, it cleans and lubricates therefore it must contain some oil.
Both products will leave a film coating on contact areas, using servisol -
the oil should be more mobile in reaching parts of the switch, I use wd40 as
a sledgehammer only to be used on V bad contacts :-)

Funny that the knobs are hard to remove. I recall the amp as being very
simply constructed. I would just leave the knobs for the next owner to
deal with.
BTW these amps are still in demand, partly because of their good phono
stages. I sold mine recently through my local hifi shop for £40.

Good call. I've got it sounding clean again, so it's 'wait and see' now.
They
are indeed very simple amps, but a decent design. I see more than a
passing resemblance to the A60 - kind of a baby cousin.

The phono stage is part of the reason I bought it in the first place,
and Santa may bring me a new turntable - hence my question.
