Hello friends
My Cousin had oneYC45, with the pedals, yes like a regular spinet organ also Yamaha had at the time three models that had the "tremolo" the R50, R100 and the R200 the largest model had 3 rotating styrofoam rectangular speakers only vertical instead of the horizontal like the Leslie.....the R 100 had 2 rotating speakers, and the R50 probably only one, never saw one in person.
I had one R200 with my Electone E10 AR, and was powerful......they where also nice looking, I used for my gigs then.
Too bad they did not continued making them.
Manuel
