Sorry I should have mentioned the pre I wanted to run the tubes in is a Rogue 66. I will also e-mail and find out what type of tester was used.
tube match?
Can anyone tell me how close the readings on tubes need to be to run in the same pre? I have the following readings, I'm wondering if any are close enough to run in a 2 tube pre.
37/36 41/40 28/36 28/32 they are tung-sol 12au7's don't ask me which reading is for what, I don't have a clue. These are the numbers written on the tubes.
