80 Watt HF PA for 27-28Mhz
This PA is a homemade copy of the famous Zetagi B150, I got a box and PL sockets from an old dead B-150
The PCB was so tired and burned so I had to construct it using no PCB at all..
At 4 Watt input I have 60 Watt out, 6 W in gives 80 W out.
This PA was also made back in 1987 before I even was thinking about becomming a HAM amateur.
Offcourse it is only tested using a dummyload :-)
