ARP 3604p

[Mike Granger]

Tim,

You might be able to take the broken springs and re-solder the loose end to the pc
board. You might be able to contact Joachim Verghese who has the ARPTech website,
and see if he can help supply new ones. If  the springs are just dirty, you can
clean them with rubbing alcohol on a cotton swab (Q-tip). Use a lot of swabs, and
throw them out when you can see discoloration after wiping a contact. Also just
playing the keyboard helps to remove oxidation, if there is any. The Moog parts
houses might be another potential source of these springs. The early Moog
keyboards used them too.
