HF-Amplifier
 
 

This homebrew 2x 3-1000Z grounded grid amplifier is designed for 4KW PEP input for SSB service on the amateur bands between 1.8 and 29MHz

     
         
 

The amplifier is entirely free of regeneration or parasitics.This amplifier is also service friendly with easy access to all components.

     
 

General components placements may be seen on the bottom of the shielded enclosure.

 

     
 

Shielded wires are used on all low voltage leads. Silver plated copper strip is used for all taps.

     
         
 

I only use oversized transmitting capacitors and shunting for the input and output circuit.
