Default Re: Head demagnetizer cassette

It's pretty battered these days. The protective plastic piece on the tip failed long ago so I replaced it with heatshrink.

I tested it recently and felt the decay may now be too fast. I must check the caps and replace if needed. Very handy tool.
That's the one I had and a cassette one that you inserted. I found both very weak since they are DC powered. You can tell if a demagnetizer works by the strength of the buzz near the poles, or any metal. There is no need for those expensive Hand-De Mag ones, the generic curved AC ones all over ebay are fine. There is usually little danger in using them, just that they can destroy VU meters. I've accidentally switched one off near the heads before, without any lasting damage - I wouldn't advise it, of course, just that it's not as dire as they always say
