[Amps] 2 x 3/400z

Wed Apr 30 06:10:01 EDT 2008

Hello PPL._!

I built a linear amplifier, based in grounded grid two 3/500z. In 80 meters
offers 600w, in 160 only 300.
the HV is 2450, in resonance down 2150.
I see, need more plate C.
Somebody has a circuit diagram with two 3/400z? For example, Henry, Swan or
Jhonson Thunderbolt.
What`s better to fed the cathode? I put a LC tuned, but I have to drive 60 w
or more on 160.
Sorri my English...
