KD4HSO here. I do RF circuit design for a living, but built the tube kit just as I have never messed with any non-microwave tubes. It’s a single ended class A with 300B output tubes. Have not measured the THD yet.

I’m not worried about the whole spectrum as I only listen to classical on it, primarily string quartets. The speakers are folded horns, so bass response is reasonable.

Anything like Dream Theater or Iron Maiden is in the car. Would definitely be solid state with a subwoofer for that.
