50 MHz 10 Watt amplifier

I found some info of a 6m amplifier I built in 2007.
It uses a VHF transistor 2N4933. I made the unit in order to give the SEM35 radio 10 Watts out instead of 1 Watt. The PA can only be used in FM and CW.

                                         Circuit 10 Watt PA for 6 m
                                            2N4933
