  1. Found 3 of these in the cabinet of an amp I just got in a trade... In this case google was not my friend- and I did try! I'm just curious :rolleyes:

    Are they magnets?

    'Ferrite' suggests that they are.

    Looks like a snap-on noise filter used on power cords.

    Here's some information on snap-on ferrite beads with application notes:

    http://palomar-engineers.com/ferrite-products/snap-on-split-beads/

    Note that multiple turns through the ferrite bead will increase the filtering. These are commonly used to reduce/eliminate radio frequency interference (RFI) coming out of (e.g. computers) or going into (e.g. audio amplifiers) devices. Often all paths into or out of the device (e.g. power cord and input cable) will need these to reduce the interference.

    Those gots da tonzez in 'em. Best use two!

    links above should have you sorted out. Previous owner probably had a single coil into the amp and thought that might fix the hum.

    Ballast or noise suppressors, often used for HF Radio stuff.
