A simple 25W fm radio amplifier used as a final stage for a 2.5W transmitter. I has a total gain of 10 dB and needs a 12V / 3A power supply. It is equiped with KT925W or BLY88, BLY89C. Use a very good headsink because this transistor get very hot Coils values:L1 = L3 = 4 turns / 1.5mm / 8mm / 10mm longL2 = 4 turns / 1mm/6mm/10mm longL4 = 20 turns / 0.8mm / on 22Ω resistor 25W FM radio amplifier circuit schematic
