[Hallicrafters] Help Please

[goldilox]

I know this is off topic, But I need help to find a schematic for a Weston 798 tube tester. It has a blown resistor thats attached to the overload indicator lamp, and is burned so bad, I cant read the value. I'd like to get this equipment running again so I can power up my SX42, & S20R. Any help you can give would be greatly appreciated. Thanks, & 73's
