From what I can remember the tranny's made for music amplifiers and sensitive equipment are specially designed to have very low external magnetic radiation. It does not take very much magnetic field emission to have an affect on an audio amplifier or a television device.
Contact the manufacture to have an original tranny, and you should be okay.
