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.
