@bkeske Hi Brian, I’ve not tried the CBS Hytrons.  I have tried very late production   (1987) Philips branded 5814As (made at the Sylvania plant) for the military (marked JAN).  Pretty decent actually when compared with GEs from the early 60s and RCAs from the same era.

 I use them in an amplifier driving the 300B output power triode.  Actually I’m using a mid-60s era RCA 12BH7A which yields a much larger soundscape (30% longer cathode/grid/plate) with nice vocals.  If the filament supply has the capacity for the additional load of the 12BH7 (300ma vs. 150ma for 12AU7), it’s an interesting test.
