maybe; maybe not

Although the 845 is a very linear tube, the requisite drive voltage often results in more overall distortion. The 211 is even worse, as it draws grid current when pushed - grid current regions tend to be rather nonlinear. Both the 845 and 211 require rather high plate voltages as well as a higher load impedance, which complicates output transformer design/behavior. The 300B is probably the better valve for Class A2 operation. SET has its own suite of issues - no natural mechanism by which to cancel even order harmonic distortions, significantly more transformer distortion and, obviously, less power delivery.

Hey, I bought a bloody valve amp to try
a hell of a big change for a high-power, solid-state guy.

I like what I bought; I like it a lot.

But, every design on earth I cannot buy.
