Testing 350B with B & K 747A
I have 4ea NOS National Union 350B tubes I was given about 30 years ago. These 4 tubes were part of a repair kit for a vintage USN magnetometer and have sat on my shelf untouched for that long. They have WE on the base.
I wish to check them with my B & K 747 tester which does not include specific information regarding this tube. I assume that testing them as a 6L6 would roughly indicate their status.
Would I be assuming too much?
I did a search and ended up in the photo section. You fellas do absolutely wonderful work. I have a homemade 6CG7/6BQ5A PP amp I use with my dads old Heathkit FM-3A. But I really enjoy building communications receivers/transmitters most.
Thanks for any suggestions or caution you can provide.
