Sixty years ago this month, the August 1961 issue of Electronics Technician carried this ad for ATR Electronics, formerly known as American Television & Radio Co., of St. Paul, MN.  The street address for the business isn’t listed, but the postal zone is 1, meaning it was in the downtown area.

The company’s specialty was vibrators, but as shown here, its product line included inverters (which undoubtedly contained those vibrators), “A” battery eliminators, and car radios.  The two radios appear to be identical, but the “truck” version of it mounts “airplane” style in the roof of the cab.  The installation took only minutes, consisting of cutting a hole in the roof, and bolting in the combination antenna/mounting bracket.

I’ve been able to find little information about the company, other than that they were involved in a labor dispute which made its way to the Minnesota Supreme Court in 1960.
