In our little hick town (Globe, AZ) there was another shop (Cody James Electronics) that specialized in converting TVs to 25 cycle for folks in Roosevelt. He would custom build a subchassis carrying the transformer, the 5U4, and filters and mount it just as shown in your example. Except the transformer was a lot bigger.
Our shop was LT Radio & TV Service. Darndest thing, Google Street View goes through that town, and the building is still there and virtually unchanged after 50 years. It's a baby goods and infant wear store now.
