Hello
I just purchased a Clapp-Eastham Radio HR type 1 tube. I don't know what type of tube was used. Also the two dials are numbered 100 (Left side) 0 (Right side) would these be original? Most pictures have the opposite 0 (Left side) 100 Right side). Any schematics availabe? I still very new to this hobby any help would be appreciated. Thanks. Rob
