Back in the 1980's, I constructed an single stage transistor amplifier to boost my 10 meter FM signal.
After converting a HyGain CB board to transmit and receive FM on 10 meters, I needed more Tx power.
The following shows the board layout and the schematic of this amp. Also, photos of the finished amp.
The actual power in is about 10 watts and the output is 110 watts.
