In the library this am and flipping thru some old issues of Audio and for some reason I remembered reading an article on how to set up/equip a disco in your basement "rec room", had to to be from the 1970s. Wish I could find the issue/article since it would be fun to read again and I'm sure some big JBL and Altec were on the list of recommended speakers. Any members remember this Audio article, or had a "disco" in the basement rec room and what speakers/amps/turntables/mixers did you use.
