Well make sense because
"Viennese radio work" (Wirag) is in Vienna, Austria. The Philips radio tubes Ges. MbH, Vienna, a subsidiary of the Dutch Philips Corporation, first took over 1936 radio stations Horny, changed its name to those in "Wiener Radio Werke AG" (Wirag) and bought 1939 the Schrack plant at the Abbegasse.
Ok I got it from here....

Better grab yourself another pair of EL3N. They are going fast. 3 pairs of EL3Ns is enough for me. Have to share it with other Elise owners. Besides I have 5 FDD20 and countless 6N7G and 6A6 and 3 ECC31.
Edit:- Maybe I should get another 3 pairs lol.
Philips Miniwatt FDD20 with Tung Sol 5998 is making me intoxicated now. Happy listening everyone.
P/S: I mean have you tried Pete's tubes?
Pss: On Joybringers aka Visseaux 6N7G now. These are crazy good too. I'm way intoxicated with good sound now.
Psss:
Agreed. There's nothing I need to change on Elise. Sounds too good with all these tubes now. Far exceeded my expectations.
