The Yamaha AN1x Synthesizer mailing list

Mouser carries both the Bourns and Alps encoders - the 24 detent 
models. 

Bourns #652-PEC11-4225F-S24   $1.68 each
Alps   #688-EC12E2424404      $2.66 each

I need to get ahold of my contacts @ Yamaha and 1) see where my 
service manual and update chip are and 2) see if I can find out 
who/where they get their encoders from.
