The roll chart on my Hickok 539A does not have test settings for the 183 or 483 tube. I am hoping someone has these settings, if not for a 539A, then for a 539B, 539C or 533. Thanks for any help on this.
Sir:The 183/483 tube is 45 with a 5 volt filament. use the settings for the 45 but set the filament to 5v...George
