Room inductance issues

Shike · 6th August 2008, 06:56 AM

Greetings,

I recently moved to a new house and have started having inductance issues with some of my gear. Namely, speakers popping when a fan is turned on or off among other things. I know some will scream that the amps regulation is poor, and probably is. Still, I don't want to rip this amp apart as there's a chance I'd sell it in the future (it's a commercial one).

So a quick question. What is a simple way of DIY AC voltage regulation to solve this issue?

Thanks

Try a few 5-10uF motor run capacitors across the line near the fans. They should help absorb the EMI.

Okay, just to make sure . . . would these suffice for a ceiling fan?

fit RC snubbers (spark suppressors) across the switches controlling the offending items.
