A few members of HAPS (Hoosier Antique Phonograph Society) have been discussing Victor’s technique for gold plating parts on early 20’s machines. Once the tapered tube, for example, has been created out of brass, was it then electroplated with copper first before being gold plated? Does anyone know the formula used for gold plating? What was the percentage of actual gold used in the electroplating solution? In some later Orthophonic machines, Victor used a technique called Gold Blush that can be removed with acetone. Does anyone know the makeup of this finish and how it was applied? Thanks, Tim McCormick
