To avoid the expense of the excellent NOS stuff try some new production JJ's or better yet, if you can find them, some pre-war Tesla's. They are a lush tube - great tone. Only down side is they can be microphonic (but not in my 128).
I also like EI 6DJ8's. Not quite as lush as the JJ's - more neutral perhaps but unlike most of the other new/recent production tubes. They are not bright, etched, or thin and way more balanced than say the EH. They might be hard to find also. I haven't tried the 6cg7 or the 6n1p.
FWIW.
