For those of you with servo (solenoid actuated play, rec, etc.) decks who were wondering about the safety of using the demagnetizers built into the cassette shell: I talked to a field service engineer from Technics yesterday since I own a RSM-45 servo deck. He said that since there is no way to engage the head without the deck power on, turn the output level down all the way, insert demag cassette, and hit play. This will *peg* the fluorescent meters, but won't harm either the meter or head pre-amp circuits. He also said that due to the fact that (Panasonic, at least) has been using an ac-bias head circuit and a head made out of a superior metal that does not absorb magnetism, it REALLY isn't necessary, especially every 10-30 hours. But he also said if demagnetizing your heads makes you feel good, "do it!" Jim Morton GenRad Inc. Concord, Mass.
