Since I don't have access to a tape head
demagnitizer (hey, all I use is
DTRS for my recording), how else could I demagnetize these heads?
Backside of a big soldering gun?
You could take it to your friendly neighbourhood TV repair place and ask
them to wave their degaussing coil at it. Or you could hold it near the
edge of your monitor, and hit the degauss button.
