UL Driver in a Power Amp?
06/07/16 at 00:44:16
How would it be to have an Ultra Linear drive section in a power amp, using a center tapped transformer as a coupling transformer, with a small signal pentode as the driver tube?

This must have been tried during the experimental years of the industry, and yet I have not seen one or heard of it.  What is wrong with it? Or is it a good design, but was abandoned to avoid paying for a coupling transformer?

I don't know of many small signal pentodes. Is there a list of them some place?
