Also, I've figured a little shortcut on repairing the felt behind the tape. If you have a parts shelf like I do, you may have the metal strips beside the paper strips of the felt that turns to goo. Remove the goo felt after opening the cartridge, cut two slits in the solid plastic wall behind where the felt went with a very sharp knife, push the metal in the two slits and bend to shape. Its worked countless times for me and I'm looking for a substitute metal strip for when I run out of the real thing. there's still lots of parts out there.

Thanx again, Mark.
