Yes! The WA is a military grade tube.
Can I substitute a 12AU7WA for a 12AU7 in a Primalina amp?
In my search for a pair of gain tubes, I cam across a pair of Laradiotechique 12au7WA military specs and was wondering if they are drop in replacements for the Primaluna 12au7 tubes that were originally included with the amp?
I know, call me a rookie!
