Theta amps are made by......Theta. I assume you are looking at a Dreadnaught or Dreadnaught II. Charlie Hansen of Ayre Acoustics did contribute his expertise in designing the original Dreadnaught.
The circuit topology in the original Dreadnaught was a collaborative effort between David Reich of Theta, Charles Hansen of Ayre, and Jim White of Aesthetix. The Dreadnaught II offered improvements that were designed by David Reich at Theta.
