it looks like the 1200s speaker enclosures, and has the same dimensions- but it is a 612s. have not had it open in years but i recall all of the speakers being original. am i to assume this thing is rather rare ? thanks for the help, ed and isaac. how do i check the classified listings, and who might this sunny person be ? sorry i don't know what i'm doing technology wise ... that's why i play old equipment.
