Hi Frank- Good point, I have often wondered about degaussing my capstan. Please, give an example of facilities that can do this. -Bruce D.

Magnetism... we all are concerned about it and the damage that magnetized heads can do to our tapes. How many of you that have the old steel capstans check them for magnetism? You should. I check every one that comes through my shop. Some have very little some have a fair amount. Tonight I checked one that really surprised me. Using a magnetometer it on it revealed that it was substantially magnetized... more than ten time worse than the tape heads, and they were in severe need of demagnetization. Unfortunately, using a cheap demagnetizer isn't going to solve the problem, but it is one that all of you must consider. You can demag your heads every day, but a magnetized capstan can seriously degrade your tapes. Magnetometers are not very expensive. They are handy to have and can tell you how well you demag your tape heads, and can show you where else magnetic fields are in the tape path. I recommend that every serious Mellotron owner should get one. Also, if you don't have a demagnetizer capable of draining the magnetism from your capstan, there are commercial facilities that can do it for you. Frank
