First, the 12BZ7 was recommended-- by me! The pros and cons and the need
to drive into less efficient (and less costly) wiring, etc., for Jeff's new lower-cost build meant that a bit of extra driver power was needed for this less expensive build-- not for what I do in my more expensive build where everything must be as perfect as possible..The 12BZ7 is controversial in that it's not perfectly linear on paper. It's good for Jeff's application because it has a high amp-factor and will provide the extra current needed to drive less efficient wiring in the build. The linearity problem is NOT really a problem. The 12BZ7 can be run where it will easily be linear enough for its intended application.
With that said, Jeff is the final decider for his amps-- not me!
There you go-- more than one way to skin a different Cat.
