Vintage Synth Repair

hi,
i bought an alpha juno 1 about 3 months ago and i had
a similar problem. one of the keys would not play
(regardless of how hard i struck it). what i did was
cafefully take unscrew the bottom of the synth and i
was able to dislodge the malfuncting key. upon taking
it out i wiped off the key's and the internal
hardware's cotact. this worked perfectly for me. if
you need any further explenation of anything else.
tell me.
