Classic Keyboard Contact Strips

[quantalume]

I'm interested to see what replies you get to this thread. I have a 45 with the same problem--a mushy key. In my case, the contact strip has a crack in the raised area. I tried silver solder to repair, but it did not hold up. I would think that you could replace the metal over one of the contact points, should you be able to find the right material and bend it to the proper radius. A little solder on each side, where the metal isn't stressed as much, should hold it in place.
