Some years ago I removed all the components from this radio to repaint the chassis and I took notes as I went. I repainted it but didn't like the color so I set it aside until I found one I liked. Fast forward to today.
Found the paint and after spraying it I started to reinstall the parts. Now I have a problem matching up the power transformer to the schematic. Schematic shows a CT for the filament winding that does not exist on my transformer, even though its the original, part number 32-7180.
I thought it might be tied internally to the CT of the HV winding since the schematic shows it that way but its not. Also, the schematic shows all the filaments as not being connected to the chassis yet the 42 tube pin 1 has a factory connection from pin 1 to the socket rivot. Is , or was, there a factory change that I don't know about?
