Luxman LV-105 Style Hybrid Amplifier 100W Simulated Project 6DJ8 (ECC88) Hitachi Mosfet 2SK1058 2SJ162

Similar to basic schematic of Luxman LV-103 / LV-105 , this project is made by only 3 simple stages: 

  1. Input stage: is a BJT cascode(Q8,Q9) with current sink(Q11)
  2. VAS stage: is a 6DJ8 (ECC88) SRPP (X7,X8) buffered by a emitter follower BJT (Q10) with MOSFET current sink (M9)
  3. Output stage: is a B class Mosfet Push Pull  with two couple of 2SK1058 / 2SJ162  Hitachi
