There are some very good control cleaners out on the market. Most of the
time, the pots and switches can be cleaned using a good quality cleaner.

Visit any of the local professional electronics parts distributors in your
area, and you should be able to find these types of products.

If the pots and controls are not able to be cleaned, then they will have to
be replaced.

Larry,

Just wanted to let you know I have the exact same Integrated DC amplifier
(Kenwood KA-9100) that I purchased new back in 1975! My unit still works
very well and I have not had any problems with my main amp volume control.
I am interested though in recommendations for cleaning the other switches
and potentiometers though since I do have some occasional cutting out on one
or both channels at low listening volumes. The problem goes away when I
flip a tape monitor, loudness, or tone defeat switch or play with the bass
or treble, so I know these are likely gummed up and dirty after nearly 30
years of use. BTW, I also have the matching KT-8300 AM/FM tuner which is
still working flawlessly!

Good luck and I'll be interested in hearing if you were able to clean this
successfully and what you used.

Bob

hi,

after 30 years, the volume pot on my KA-9100 amp seems to be wearing
out.

i have read much on cleaning pots, (done that), and replacing pots.
my searching has found little on repairing pots.

'Secret Life of Pots' sailed right past the practicalities, (which i
need), and into the technicalites, (which i don't understand).

i was hoping someone had found a site with a faq or a howto on
repairing pots which they found useful.

any pointers or suggestions would be much appreciated.

thanx,
larry
