New interconnects or some NOS tubes for rolling?

tubes! but make sure you are getting some decent and to offer another flavor.

What kind of gear are you going to be rolling in new tubes. Some circuits are friendlier to tube rolling than others and synergistic issues are in play, too.

"I can either get some Blue Jean or Zebra interconnects or some 12AU7 tubes for my amp. What are your thoughts? "

Tubes can be inexpensive and can change the character of how an amp sounds.

Don't forget substitution rules...all the tubes in bold below...can operate in place of a 12AU7.

I think the question was not presented with all the facts which would help everyone give more qualified answers. He already has some pretty darn good front end tubes NOS tungsol 12AU7's. IMHO once you have some good quality tubes in the front end the differences kind of blend together and become obscure. I also don't see anyone asking what IC's he has now.... He is currently using bargain bin stuff from parts express. IC's can and do make a huge difference since they are handleling the signal at it's most vunerable points.

What Craig said.

It is a Dynaco ST70, and I am waiting for some RCA cleartops.
