Mine is currently set up for early breakup, but I have a "clean" EL84 that I got from Eurotubes, and several different 12**7 preamp tube flavors on hand, even down as low as the 20% gain 12AU7....
Vood, have you ever looked into the mercury mod?

It's sounds right up your alley. Although it costs $300 to get the kit.
