I put the Tung Sol pre's in the NT and I can't really say I heard much if anything different from the EH's that were in it. Will see how changing the power tubes goes.

This one sounds interesting but expensive:

The RFT EL84 tube is a rugged tube that was made in East Germany in the '70's. This EL84 tube is clear and detailed without being bright or etched. The RFT EL84 tends to overdrive easy making it a good choice for hard rock and blues. $65 for a matched pair.

The reissue Gold Lion sounds interesting too but may be to wide to fit in the NT:

Clean tones are chimey and sparkling with single coil pickups and a bit darker with humbuckers. The overdrive on these tubes is smoooth. No gritty, raspy tones, the tubes have just the right amount of compression to track with the overdrive and keep it beautifully controlled while blooming nicely as the note fades out. This produces a very nice organic sustain. "These tubes have a slightly larger diameter than other EL84 tubes so they can not be used in Marshall DSL201 or DSL401 amplifiers, or reissue Vox AC15 amps.
