Hum From Speaker


1. I hear a low Hum from my speakers.
2. When I increased the volume the Hum does not increase.
3. I disconnected everything from Amp except the speakers and I still hear the Hum. Not even the interconnects were connected to the Amp. Just the Amp plugged into the wall with a cheater plug as a test.
4. All other components were disconnected from the wall.
5. I can't hear any Hum from the Amp unless I put ear right on the Amp.
6. My Amp is a Sunfire 5x200

Does not seem to be ground loop.

Any Ideas? Any Solutions?

Thanks ahead of time.

You were right about taking it to another place. I guess I was holding out hope the Ebay guy was telling me the truth.

Once I have the final charges, I will file a complaint with PayPal and Ebay.

Thanks for your help.
unfortunately, paypal and ebay will only step in to get what you paid back....and then only if you send the original product back to the seller.

If you keep the product and expect ebay and paypal to help you get the repair costs...it won't happen.

So...just pay the money to fix it and enjoy it....but don't expect anyone to pay for the repairs. Welcome to EBAY....

I guess I can ask the seller to do the right thing and pay for the repair. If he doesn't then I settle for giving him the feedback he deserves.

Either way I will enjoy the amp. It sounds really great except for the hum. Thanks for all your help. I will post the results of the repair.
My repair guy just changed out the caps and it still hums. He found on one of the bridge rectifiers that it has large ripple on the positive side. He is going to try to change out the bridge rectifiers, but if that does not help he does not know what else to do.

Any opinions?
New Caps and Bridge Rectifiers did not help.

So I am sending to the Rita Helm Carver/Sunfire repair shop. For a flat fee of $175 plus shipping they will restore the unit to new condition with a one year warranty.

I will update the post when I get my amp back.
