Can the old tube tester models like B&K or Hickok test the 300B, 211, or 845? I have an amp and pre-amp that use 6SN7, 845, 211, and 300B, so I would like to know if the old models can test these tubes.
I'm thinking of the Amplitrex but it's expensive. For the 845, 300B, and 211, how do we know if the tubes go bad wihout the tube tester?
Thanks!
