Hi, I have an ac switch conneceted to my power amp cooling fans(fans are not part of the amp). If I run the amp hard I turn on the switch to start the fans. I get a popping sound in my speakers as the switch is turned on or off, regardless of the amps volume setting. What can I put across the switch to attenuate the arcing noise? a mov or a cap? And what values? I think the fans draw about 60-70 watts. Thanks in advance.
