Hello Mile sir,
Having built B500 I m impressed by the performance of the amp. The next step is to get the most juice out of my 2.5kva toroid and 2kw speakers.. I have gone through this thread and finally decided to built H900. What I couldn't find is H900 schematic with 8pairs of output transistors to support 2ohms and 16 ohm loads. Maybe I have missed it. So I am looking for H900 triple emitter follower schematic/circuit . I request Mile sir or diy members to please help me with H900 tef circuit. Thank you :-)
