What about tiny DC imbalance?

The Amity/Karna designs rely on a shared cathode resistor with a dual triode PP topology. Assuming the triodes are perfectly matched, I will get no DC imbalance.

What kind of real world triode-triode matching can I expect (lets assume JJ ECC99 for now), and what will a "no DC imbalance" transformer allow me to operate under?

Or would I be better off with separate cathode resistors, one of which is adjustable?
