There is no "one tube DHT amp." There are only amps with gain in one box or two boxes.
Your 6E5P tube is not so special. People have been making WE437 spud amps since the 1960s. There is a class of amps that use a high-gm tube driver and a DHT out...

about power factor correction is completely accurate and very much makes sense.
