SOURCE: gas dryer makes loud hum

Sounds like you may have a motor issue, they can get lint trapped inside, and it causes the motor to overheat, and eventually go out. You can remove the top, then the front, and see if thats the problem. Usually, once the motor starts making noise, its time to replace. Right now, the packings in the motor are cold, and once they heat up, they stop making noise, so it could last quite a while.

SOURCE: Sears Bottom Freezer Refrigerator - Loud humming noise

That sound is usually your icemaker calling for water. you can turn off your icemaker by lifting the little arm on the icemaker. As the icemaker calls for water the valve will be activated and will hum. This sound is usually not very loud. If your valve is making that much noise you may consider replacing the valve. The part number for you water inlet valve is #2315533 The retail price is $60.18 . I do have these on hand and available to ship out today if you need one. Please just let me know. You may also consider replacing your filter if your refrigerator has one. Thanks and I hope this will fixYa

SOURCE: Deville 212 overdrive channel making Loud humming noise

It sounds like a filter capacitor(s) has failed. The electrolytic caps dry out and cease to perform allowing unfiltered power to reach the preamp sections and get amplified.

Being this is tube with high voltages, an experienced person should work on it due to shock danger.

I assume you checked the tubes for shorts as well as emission since a heater to cathode short could cause this as well.

Misalignment of the belt, incorrect belt, worn or loose tensioner, Too tight of an adjustment (many service centers do this on purpose so when the belt breaks in it becomes properly adjusted, I do not believe in this philosophy), The belt is actually one long belt called a serpentine belt.....
