Boy, and I thought my SX-16 was a P.I.T.A.! Now, I'm happy! I was looking through the Hallibook (2nd. edition) at the various styles of R-47 speakers that Chuck shows. Turns out that mine is type of DIFFERENT. It's gunmetal silver, dark grey die-cast front, with a RED button, and the 60's style "h". Yet another variant, eh? Tom - WØEAJ
