Q1 - Q8 Mosfet IXYS 82N25P
R1 - 1k C1 - 104 T1 - Spliter 1 : 4
R2 - 10 C2 - 473 T2 - Toroid Bifilar 25 T
R3 - 470/1w T3 - Tubing 1 : 9
T4 - Combiner
The circuit work with four push-pull modules ,combiner and splitter The amp as shown needs 75W of drive for full output. The splitter wound on a small tubing or toroid transformer with about one turn pri. and two turns sec.
