i recently got an old sunn PA speaker from my dads friend who bought awhile back for his kids but never used it. its a model 8, or so it says, but the most i have seen throughout tons of searching online, is a picture in the 1979 catalog of this site. i havent seen a single thing more than this. Does anyone here know about this amp, or where i can find out about it? i know almost nothing about it except the infomation given on the back panel.
