Re: K-S2 Aperture block failure repaired

Firstly,  well done!

Going back to my sound recording days, a build up of residual magnetisation was a common problem on audio tape recording heads, it caused a background grumble and other. It was routine to demagnetize the heads with an iron cored copper wound coil with an AC current which would "shake" the molecules around until their pole orientation was neutral.

From what I read here maybe the problem could also be cured by demagnetizing the offending core piece, it's a shame that many bodies find their way to the dumpster because of it!
