This is for a pair of RCA 12AU7 black plate tubes. Square getters.
I bought these last year from Brent Jessee, I really didn't use much, the gear that used 12AU7's is all gone now, so I'm just cleaning up. See test results below. I remember these sounding very nice and full, very rich sounding tube, but that was in a preamp circuit.
Asking 50 shipped to lower 48 others please ask.
