Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: Class A (???)

I was thinking of cascaded "long-tail pair" differential amp stages. With a current source the "tail" does not need to be so long and inefficient.

The LTP is sometimes used as a phase splitter. Sometimes the common (shared) cathode resistor in a P-P output stage is left unbypassed; you might call that a short-tail pair diff amp. :^)
