Moog, Arp, early Sequential stuff) had gold-plated key contacts and bus bars. On
the Analogue Heaven list someone mentioned using gold-plated guitar or bass
strings to repair these when they break... that might work for building a new
set of contacts as well. The strings are made by a company called Maxima.
