I've seen EL34 tubes used as 300B drivers, but never KT88. Would be interested to see that, too.

I designed and built this three stage amp a few years ago. Ultimately I believe that there are two weaknesses to the design: the driver tube should be direct coupled to the output tube and a two stage amp sounds more transparent. There are several good tubes to drive a 300B with a single stage.
