Adopting vacuum tubes plus a solid state circuit(6J1 tube are used for preamp section and very famous United State NS amplifier chips LM1876T for output stage). The audio signal will go through a pair of vacuum tubes first and then the solid state.
You will have the benefits from both worlds —vacuum tube’s warmth and solid state’s speed.
