HPA1 Hambuilder 40m 100 Watt RF Linear Amplifier Prototype

Linear amplifier for HBR1HF and HBR602
*. 2x IRFP150
*. 10-15 Watt input (match with HBR1HF and HBR602 power out)
*. 80-120 Watt ouput

I like QRP much, but sometimes on bad QRM we need more power to make sure there will be no complaint from some one with low gain audio sensor (lol). This is may be suitable also as a set line for HBR1HF or HBR602. ATU will be next set line.
