I've owned Crowns since around 1970 and JBLs since my Dad bought his first one in 1957 but it wasn't until I joined this forum years ago that I got into the acquisition of Crowns as a hobby unto itself. I blame/credit a departed member here, Tom Loizeaux who shared my enthusiasm for Crown amps and introduced me to the PS-series:
A quick count of what I have now would probably be close to 15 Crown amps from D45 to Studio Reference II.
