Amp fuzzes and crackles, help?
Question:My tube amp produces a fuzz and distortion of sound even at low volumes. There is also a loud crackle at high volumes. The power tubes have been changed recently. Could this be a speaker problem?
Answers:
It is possible that your speaker cones are old and dry and/or the wire connections to the coils are not solid anymore (broken wires, loose solder connections, etc...) causing the noises. You might also try reseating all of your tubes in their sockets to help clean up any corrosion that may be between the pin connections.
Another possibility is the carbon volume control itself. Over years the carbon in the potentiometer gets old, worn and dirty and can cause all kinds of noise issues. There is some spray cleaner that you can get to spray inside the potentiometer and clean it up and make it sound like new again. You would have to check at some good electronics shops to find it. Can't remember exactly what the names were anymore, and the old stuff may have been replaced by newer stuff (I remember one called "Blue Stuff," I believe it was more of a contact cleaner, but may work on carbon pots too.)
Hope that helps. Good luck.
could be your potentiometers and if it's them you need to go to a electronics store and get some spray to put on them, work the volume and other knobs back and forth as you spray it on them.If it was your speakers the spider has failed and new ones are only solution.if this is a tube type amp then its even possible you are getting problems from an intermitten tube that has or is failed,if it's transistors it's entirely different.
