It is quite critical assembly and RF power transistors must be mounted on heat radiators and handled with utmost care.
The coil L1 is formed by 04 turns of wire of 1 mm in diameter in the form of 8 mm diameter. The coil L5 is formed of 07 turns of wire 0.5 cm in diameter in the form of 6 mm in diameter, the coil L6 is wound wire of 1 mm and consists of 03 turns in the form of 10 mm diameter. Finally coil L2 consists of 04 turns of wire of 1 mm diameter in the shape of 10 mm.
The transformer T1 includes coils L2, L3 and L4, and these coils has turns of one wire of 0.5 mm figure 2. In this same figure we have to identify the terminals of the transistors. The capacitors must be ceramic disk type or plateau and resistors are 1/4 W.
