Question about cleaning an amp's dusty contacts


Dear Friends:

I have a YBA Integre DT amplifier that I would like to sell. The unit sounds wonderful, but you can hear a static-like sound whenever either the stepped volume knob or the source component selector knob is being turned. Once the volume is set or the source component selected, everything sounds perfectly normal.

Someone told me that dust had gotten into the contacts, and that all I needed to do was open up the unit and spray the respective parts with an electronic contact cleaner spray (sold at any Radio Shack).

Does that sound right?

I am afraid of doing something that could make matters worse (in other words: if it ain’t (truly, completely) broke, don’t fix it).

I have already tried to sell the unit twice before, for a very reasonable price, but I suspect that mentioning the problem is scaring away prospective buyers. I bought the unit knowing that it had this problem; others might not be as tolerant. Ethically speaking, I have to mention it.

Any advice would be most welcome.

Many thanks in advance for a reply.

Rat shack contact cleaner. You may not even need to open the top, you may be able to get enough down the shaft from the front. Also, sometimes just moving the control back and forth rapidly, several times in succession will do it. Neither would work on a digital control, tho.
