My name is Keith Robinson, I worked and sold audio equipment (home and mobile) in an audio store named Audio Village in my home town of Cape Girardeau, Missouri in 1975 -1978. We sold Technics, Kenwood, A/D/S, JBL, Dahlquist, Magneplanar, Harmon/Kardon, Phase Linear, SAE, Sanyo, Nakamichi, Teac, Ortofon, Grado, Shure, RG Dynamics, Dual, Garrard, Craig, Polk Audio, Jensen, and craziest of all; LiteLab Disco Lighting equipment.
Welcome to the forum! I love watching the vintage audio commercials on YT, audio was such a huge part of life for just about everyone. Magneplaner is a couple cities over from me, I posted their factory on the factory thread. Back in the late 90's I worked for the remnents of Nortronics, they were mostly known for replacement tape heads but they also had demagnatizers and bulk erasers.
