Yamaha "Arranger" keyboardes from '83-'84 are still out there,

and often in FINE condition, sometimes for sale by the original owner.
I just picked up another (PS-55) for $65 w. pwr. supply and Operator's Manual.
I now have FOUR working and one for parts. I love 'em dearly! ~ I'll play this one at the Sunday Jams at 163 Main St. @ Gerrard St. E. ~ BTW, their model #s are PS-35, PS-55 and PC-1000. Their "jazz organ " voice sounds SO-O-O Hammond, especially through a Leslie!
