4CX250B 2m linear circuit? (Class C ideally!)
 

In class G or H amplifiers you do vary the supply voltage. But not much
out there on class G or H amps. I'm suprized nobody mentioned class G
or H.

I have two 4x150G's These are 1000 VDC plates, and coax style
connections. I'm running:
at 144mhz
800VDC on the plates dual input choke supply
375 on the screens regulated and protected
-50 on the grids, adjustable for any class, regulated and protected
grounded cathodes
Push pull
With a strip line low pass filter for 2M on the output -60db
