lately 've been having trouble with the vol. knob on my Yamaha
integrated amp.
It's about 18 yrs old but haven't had much problem before. the problem
is i'm not getting any sound from the unit...until i tap rather hard
on the knob itself. a few pops and it comes back on. Is this something
a cleaner could take care of? or need a new potentiometer?

Might be cleanable, might require a replacement. Cleaning is worth a
try... buy a good control cleaner (either a "zero residue" type, or
the type which leaves a small amount of lubricant or contact enhancer
behind), squirt into openings in the control pot while rotating it
through its full range of motion (amp turned off and unplugged, of
course!).

If that doesn't help, you'll probably need a replacement pot.

Symptoms of this sort _can_ result from other problems (deterioration
in electrolytic coupling capacitors, "cold" solder joints which have
become intermittent, etc.) but the pot is the likeliest culprit, I
think.

J. McClendon:
From what you have described the problem may not even be caused by the
volume knob (pot) but rather could be dry/cracked solder connections,
faulty/dirty speaker relay, faulty dirty source select switch.... tape
monitor switch.... or other switches, etc, etc,....... do not keep
operating your nice Yamaha amp with this problem .... if you keep nursing
this along, it will not heal itself, but rather the problem may get worse to
the point that no amount of "tapping" will solve the problem and expensive
parts will start failing....
At the very least you should TAKE it to a repair shop for a repair cost
estimate so you can make an intelligent repair decision with facts.
A tech really needs to see and touch the unit in order to provide you with
something better than wild guesses.

First try giving it a spurt of CRC turning the knob forewards and backwards
a few times. If that does not fix it get it repaired by a service
technician.

A volume pot usually acts different on either channel, and can usually be cleared or changed
by simple turning.
