WARNING !!!Lethal Voltages are present inside theHeathkit SB-1000 linear amplifier enclosure

even while the unit is disconnected from the AC power source. Read all documentation before

operating the SB-1000, observe all cautions and warnings, and Do Not defeat safety interlocks. The

buyer assumes all responsibility forsafe operation of the amplifier.Failure to heed these warnings

could result in death of the operator!!!

The Heathkit SB-1000 linear amplifier (newly assembled from kit)is capable of operating on 160,

80, 40, 20, and 15 meter Amateur bandswith an output of 1000 watts in SSB mode, 850 watts in

CW, anda reduced output on 17 meters (600 to 800 watts). The unit is fully tested and aligned

for all available Amateur bands. The amplifier operates in a class AB2 ground grid circuit with a

single 3-500Z fan cooled vacuum tube and requires 100 watts (85 watts typical) excitation for full

RF output - the 3-500Z vacuum tube has approximately three hours of use on it. Analogue metering

circuits provide an indication of High Voltage, Grid and Plate Current, and Relative Power Output.

An impedance matching pi network for each band is switched into the circuit by a Band Selector

switch. The unit is wired for 240 VAC with a current requirement of 8 Amps but can be changed

over to 120 VAC with a current requirement of 15 Amps if desired. All assembly manuals, aligning

tools,and documentation are included in the selling price. The 3-500Z vacuum tube ships separate

and requires finial assembly. The buyer pays for shipping with a combined weight of 60 lbs.
