when i adjust fan in room it makes clicking noise in stereo,please help.

 

At first brush, it seems some kind of filter would be helpful.

Can you give us some detail about your stereo?

 

dont know what kind of stereo yet, i am high voltage electrician ,over 91 v ,going to friends house.

 

There are high frequency filters, often called conditioners, that will filter out high frequency noise from an AC line. This might be applicable for your problem.

It could also be RF noise too, you're going to have to see the setup to figure which it is.

Dirty switch contacts would be my 1st guess.
