Black anodizing, voltage doubts


I was reading your response in letter 43248 and I'm interested in know more about electro coloring anodizing, at this time I'm coloring with Tin solution, but I have doubts about output voltages, I have an 3000 amp 30 volts AC coloring power supply by Dynapower, with five steps:

1.-dwell time
3.-stage # 1
4.-stage # 2

Where can I get "Electrolytic Coloring of Anodized Aluminum Using Tin Electroltyes" by Gohausen & Schoener (Plating & Surface Finishing, Feb. 84) ?

Or a newest ?
