The very rare Ra50 was Yamaha’s answered to the Leslie. The great thing was in a travelling band. It was half the size and it was more durable. You could still get that rotating speaker effect but Yamaha decided to do it a different way. There are a few nicks in the cabinet This unit has a slight hum, but it could be just a grounding issue, unit runs according to spec. It is extremely heavy, so shipping is going to be expensive. But if you’re in the Winnipeg area, I could probably bring it there.
