When I moved in to my present home, after many months of investigation including setting up power quality waveform recorders, I traced blowing bulbs and hum to what I believed to be a insulation break-down on the pole-mounted distribution transformer windings. Sure enough the local utility checked out the transformer and promptly replaced it.

Thanks Socketman. My wife and I built our new home on our rural property about 13 km from a city in Alberta. Moved in June last year so the wiring is new. No TV cable connection, just an Xplorenet connection (think satellite) to a wireless router. We did have a new power pole provided by the utilty company, Mojo, so I'll check what's happening there. I'm not new to this forum but I created a new user name due to a new email. I've read a lot of posts by you guys and thanks yet again for your advice.

Enmax in Calgary and AltaLink have both encountered ground rod corrosion from the acidic soil in Alberta. Your installation is new however so I wouldn't expect any grounding issues. It's certainly worth checking though.

An input transformer would help. Equi=Core balanced power supply.

I had no end of issues with hum and certain components. you need to try unplugging everything else from the wall. I was getting a hum from a faulty power brick that my media center pc was using.

silly part was it wasn't even plugged into the pre-amp. It worked fine with my cheep pioneer receiver
