I have some nice 12AU7s here:
RTC French-made 12AU7WA from 1958 with square getter. Gray plates and twin silver top getter support. French signal corps markings, similar to the "S" type tubes above, factory tested for noise and uniform output. Earliest version of 12AU7 with 12AT7-type plates - 155/pair
Ken Rad shiny black plates with major uber-horseshoe getter - 96 shipped per pair (2 pairs available, 1 extra single available)
Tung Sol D getter 12AU7 from 1950s - 65/pair
All prices shipped (USA), tested, and matched on Amplitrex AT1000.
thanks
