Bambi-- in the mid 80s, RAM actually selected their tubes from very decent stock; I have a pair of RAM GZ34 that are Blackburn plant Mullards. That said, I can start by eliminating some of the usual suspects. Its not a tung sol, as they are all top getter and instantly recognizable.(Tung Sols have the red/brown base you describe, though) Your description of the mica and single plate getter says American Sylvania/Phillips of late 70s vintage, but again that base color would be atypical. What shape is the getter ring? If it is square, that would suggest GE or Raytheon, but they didn't make this tube; it is unlikely but not impossible that RAM would re-label a relabeled tube. Sylvania/Philips consumer (not JAN) is my best guess. BTW, you can easily get away with JAN Phillips or even Sovtek for this tube-- this is the one Sovtek tube that I truly have faith in, reliability and durability-wise; as it is voltage regulation, both would serve as well as even 1952-60 Tung Sols (they won't last as long, of course.)
