You have two clues here to help you solve this problem. First since the volume control turns up the noise, whatever causes this noise is before the volume control. You don't state that the noise is in one channel. If is in both, then a part found in either of the channels can not be the cause. If it is common to both channels you are looking at something common to both channels that is causing it. For example something in the power supply?

It sounds like a power supply problem. If you can find the power supply board, look for bad solder joints, look for caps that might be bulging on the top, could be a leaky cap. I'm not sure of your power button, but it could be faulty.

The Deluxe may have more efficient speakers....which would cause it to sound louder. Also, the EQ settings could play a part in this. If the EQ's aren't set the same there could be a noticeable difference in sound.....usually the mids can have quite an effect on overall amp volume....

I would look for crossed wires or shorts on the board itself as a result of overheating. They will look like toasted circles around the pins of the board. You may not have been the first to open the amp and make a repair.

Hey madmedia63

Good old amps these. Fixed a few over the years. I would expect dry solder joints in and about the channel switching. If you got a mate with soldering experience, he da man to help you sort it. Hard to help you anymore without actually looking inside the amp to see what's going on. But that's were I would start at least. Way round it I guess is to use a distortion pedal. Go for a metalzone to get similar sort of distortion. \m/ riff out ;)

It sounds as though the ground connection to the fader control has gone missing. Check with a meter.

You can transfer the songs from the old iPod to the new iPod using the iTunes Software installed in the Computer. It is required to connect the old iPod to the Computer and sync the songs to the iTunes Software. Select the Sync iPod option from the File Menu. Once you sync the songs from the old iPod you can connect the new iPod and Sync again to transfer the songs from the iTunes.
