The 6 Meter 1KW AM Transmitter





                The 6 Meter 1 Kilowatt rig is a converted G.E. RF Amplifier Deck. This deck has a pair of 4-125A Tubes
                 in the output section, a chassis mounted T-R relay, has its own blower mounted on the chassis. This unit Runs
                 about 350 watts output on 6 meters. It is also driven by the Heathkit Seneca 6&2 transmitter, through a HB
                attenuator made especially to lower the output of the Seneca, or the E.F. Johnson 6N2 exciter.
                The 4-125A tubes are supplied Filament voltage at 5.0V @13 amps. adjustable by variac control. The High
                voltage for the  plates is 3000 VDC at 200 MA. available from a "Rescued Savant Power supply deck", the
                primary on the H.V. transformer is strapped  for 115 or 220 and is running on the 220 VAC currently. The
                screen and bias supplies are regulated and adjustable.



                This unit runs in class "C" and also class "AB2". I selected meters to monitor the proper operation of the amplifier
                The grid current meter is a 0-100 milliamp meter, the screen current meter measures 200 milliamps and there is a
                10Hy 110 milliamp choke in the screen line to the amplifier. The plate current meter measures 0 - 300 milliamps.
                 If you get the chance to acquire one of  these don't pass it up, its a great way to get High Power on 6 meters for
                 minimal effort. The units are virtually indestructable and will run in CCS mode all night long. See you on 50.4 MHZ
                 and listen for the WB2FCN Beacon on 50.25 CW when you hear that you'll hear this "Mighty-Monster"

the Amplifier Module.


















The antenna relay assembly, does this
look familiar?




You need to monitor the drive to this rig
so I use a 100 watt slug between
exciter and amplifier





A 250 for the Johnson 6N2 and
Heathkit Seneca
direct to antenna.





And for the full output of the
amplifier, mid-scale of course!
