Jim,

I turned on all the lights and appliances and one by one, turned off a breaker and looked for the effect. Here's what I discovered.

My main panel is a 125 amps and its length is horizontal, with the main switch on the right, breakers on the left. Most of the breakers are on the top row. The breaker closest to the main switch, on the top row, is for the fridge and microwave. The very next breaker, adjacent and to the left, away from the main switch, is the breaker for the audio circuit. The lights for the kitchen are on, yet, another circuit, to the left of the audio breaker.

Also, the panel has two ground cables and everything is as tight as can be.

So, I'm not sure why, then, but when I turn on the amp, the lights in the kitchen will dim, momentarily.

Once I choose surge protection/power conditioning, I'd like to build a dedicated circuit. I'd actually like to take a picture of the panel and send it to you or place it on here, so you can further guide me.

Can the draw from the amp, initially, be that great that it affects all the circuits?

Since I removed the buzzing doorbell transformer, the amp does seem quieter. I had it on for several hours, yesterday and before I went to bed, in the quiet of the night, the difference was noticeable. So, this is good.

Again, thanks!

John
