Worked like a charm. It completely demaged my calipers my chuck key and one of my screwdrivers in seconds. Highly recommend.

Bulk tape demagnetizer might be an obscure term for members under 35 years old. I can't explain the concept of early sound recording very well but basically the sound got stuck on an iron impregnated roll of tape. How and why it stayed on thereare mysteries that have not been solved to this day, as far as I know. You needed a demagnitizer to get the sound off the tape I think. The tape came in various formats, large reels, 8 track cartridges, cassettes, maybe more I don't know about. Just imagine how small the tape recording device is in my Iphone . I'll bet the tape is smaller than a hair. How can it hold so much music? Would someone take their Iphone apart and verify this theory please?

Thanks, Kevin J.
