I recently sent mine in for service (my fault, moving) and Paul replaced the chinese tubes with EH 12bh7's. Much, much better even out of the box.
I tried some E80CC's from Brent Jesse, but the TADAC didn't like them (tubes kept shutting down), and just traded them for Telfunken rib plates. Don't like them at all out of the box. Edgy sounding, and not as sweet and airy as the EH 12bh7's.
I'm new to tubes, and it seems the Tele's might need a bit to break in....
