ONE KILOWATT HOME MADE HF LINEAR AMPLIFIER
My FIRST PROJECT REALIZED IN THE 1980
.. and after 34 years, still works fine …!!!
The RF Input Tuner
The Antenna relay and the connectors 
The ferrite rods with the Filaments chokes
The power supply inserted in a Midi-size computer tower
internal view of the power supply 
the capacitor bank with the voltage equalizer resistors
.
this is the first version with 2 Valves PHILIPS QB-3,5/750
. and this light warms the heart … do you agree?
…and now…..I will present the LAST VERSION WITH 2 VALVES 4-400 BY EIMAC WITH STELLAR ANODE 
…the final result….. .
…and still works very well…!!!!
NICE VIEW ,THANKS,
GEORGE
SEI UN GRANDE PICCOLO SALUTONI PEPPINO
