The Dynaco Stereo 70 tube amplifier uses a circuit arrangement based on the Dynakits Mark II and Mark III which has become world famous as one of superior quality while essentially simple and trouble-free. The new 7199 tube is used as a pentode high gain voltage amplifier directly coupled to a cathodyne phase inverter. All parameters are adjusted for minimum distortion. This type of phase inverter has the unique advantage that its operation is independent of tube aging so that no adjustments are required in maintaining optimum performance.
