Tube Testing

I was not able to test the 41 & 84 tube on a recently acquired 41-280. All the other tubes fit nicely in the loctal receptacle and could be tested. This tube tester was made in 1960 and includes older base designs but not for the 41 & 84 base. Any suggestions, thanks

No, it did not use photo-finish. It is veneer with the shading on the front of changing darkness.morzh — 07:52 AM
