Thanks, David. I'll keep that in mind. I remember reading that article.
Any idea app. when it appeared? Otherwise I'll dig through the back

For my information. If one has to go to that much trouble, wouldn't it
much easier/better to just replace them with new? Except maybe in antique
type of instrument? Just wondering why one would take that much time.
