80 Watt HF PA

Nice job rebuilding the guts of the transmitter. Why buy when you can rebuild.

“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 :-)”

    I’m intrigued by your photo of the amp-hack.
    As a ARO, I like more info about it.
    Will it cover effectively 160-10M ?
