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 diode bridge
the capacitor bank with the voltage equalizer resistors
BAND SWITCH and the TANK COIL
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
