All this was was something that I had tossed around with my friend. He has Rogue mono tube amps and a Rogue tube pre-amp that he replaced the power cords for. Yes, I know the Rogue just plug in and don't require opening the case. Made a huge difference. We also have a friend that used to design and test amps and told us what a difference the power cords can make. The standard "computer" power cord that comes on/with just about every single piece of audio equipment is garbage and passes along all sorts of noise.

It was just something that we were going to try if the cord was clamped down and not soldered into place.

The noise he was hearing was not from a vacuum, or any other electrical appliance in the house. It was a combination of the outlet and the powercord itself. He replaced the outlet first, still heard the noise and then built new cords and it made a vast improvement.

I'm not going to have time to open my 1050 up and take a look inside until the middle of Feb, so once I see how it is connected I will make my decision then. If it is not clamped down I leave it alone.

Thanks for everyone's concern and ideas, I do appreciate it.
