5814 = 12AU7 or 12AT7
I was of the understanding that a 5814 is a mil spec rugged version of
the 12AU7 but in my tube tester settings charts the setup for the 5814 is the same as the 12AT7 not the 12AU7. The difference is the LOAD setting is lower for the 12AU7 but the same for the 12AT7 and 5814. |

Amazing, I guess with about a few thousand tubes in there it happens though. Thanks. |
