Amp noise

[Pure_Brew]

typically 121.What sort of filter, other then what's in my Belkin, do you mean?

 

[speakerman1]

Same kind of filter. Has it done it again?

 

[Pure_Brew]

No it hasn't done it again. But this and past issues really makes me want to investigate

 

[Pure_Brew]

Ok now. All quiet this AM. Everything was off but I could hear the Belkin buzzing. The breaker panel is also in that room and it was buzzing to. I put my ear close to the panel and noticed it coming from one point. I started hitting breakers. When I got to an upstairs bedroom breaker the noise in the panel went silent. Flipped it back on, still silent. Belkin went silent too. I have to look to see what's plugged in up there, could be the breaker itself?

The panel actually has never been this quiet, as it is now.

 

[speakerman1]

When you tripped the breaker. What was making the noise may have not come back on.

 

[Pure_Brew]

Yep I know. When it comes back, I'll get my son to help me unplug things one at a time up there.

 

[speakerman1]

It is something that doesn't reset itself when the power is turned back on. A fan?

Bad breakers can do te exact same thing you are describing Joe. A small, continuous arc can give off a lot of RF and EMI interference.

What type of panel is it? Square D, Pushmatic?

The panel should never make noise.

Jim

I second that motion. LOL

 

[Pure_Brew]

Could be at the heart of the problem.

 

[Pure_Brew]

Isolation Transformer?

Is there a way to isolate the power for the system and provide a clean waveform? I don't need big power, somewhat affordable would be good. Tripplite?

[speakerman1]

500 watts is not much. I'll have to check a trans I have. It is bigger than 500. I think it is 1500. Send me all your gear but the Snells and I'll try them out. LOL Do you have anything with a variable output? Not a pre. So you can go straight into the amps from a source? Your Bellari.

 

[speakerman1]

Let me see if someone I know can design a passive AC filter.

 

[Pure_Brew]

I can go straight to amp from the bellari or my phone. The Jolida has only a passive attenuator but it can be bypassed via a switch to use as a straight amp. Why?

 

[speakerman1]

Just thinking. Never mind. LOL

 

[laatsch55]

Get us all excited......then.....NEVERMIND????????????????
