Reply To: Test for Rogers Majestic radio tubes.

Too bad you didn’t have a 9-55 otherwise I could scan and send you all of my cards. They say the 9-66 was first made in the late 40’s and given this mine is probably as old as the radios I have. Other than this I have two Heathkit tube testers with the rolled up paper you scroll through by turning knobs. I just need to find a tube tester to test these.
