Fun flash back there buddy. I was working for the so cal Zenith distributor...though TV's were our main thing they made some really nice mid level stereo system and came out with a discrete quad system that had both a phonograph and 8 track player that were quad. One of the buds we worked with bought one and we all went to his shack to get stoned and listed to DSOTM and Echoes on it...Getting loose on Matuese (Portugese wine) and stoned on some good California grass,,,Dem was the daze. That discrete quad shit was awesome.
