I was Googling Pacific Stereo and found this info: Pacific stereo was owned by CBS from 1972 to 1983. Pacific Stereo purchased in January 1983 by Burk Mathes. Number of stores reduced to 64 by 1986. Pacific Stereo files for Chapter 11 on May 15, 1986. On Sept 25, 1986, Pacific Stereo reorganization plans fall through. Oct 1, 1986. Liquidation begins.
