Hi all, working on a W W Grant 5 tube peanut tube radio . Looking for any info on it which may help in getting it fired up. Sketched out the diagram and looks like a series parallel filament circuit, but not sure what voltage the filament control can handle. It uses 4 215A tubes and one UX120. there is 3 grid leak resistors but unknown as to there real value.
Again any info would be helpful
Thanks Martin…………………
