HF Amplifier
Covering 2 MHz to 30 MHz

(EQP) AM-3007/URT
HF amplifier covering 2 MHz to 30 MHz. One watt input produces 100 watts output. Front panel metering allows switching between plate and cathode current and input line voltage. Also separate meter for forward and reflected power. Zero to 100 watts forward and reflected and 0 to 30 watts reflected. Requires an 8223 driving an 8116 tube, not included. Input network is selected by a motorized turret assembly based on frequency of input signal - possibly selected by control signals from transmitter. Motorized load and tune output network controls.

Tube cooling is via conduction to a massive heat sink on the front panel. Front panel switch offers "Normal / Bypass" operation. The unit is completely enclosed in a formed aluminum case that fits a standard rack mount. Loosening the six front panel screws allows the unit to slide out of the case for easy access. Operates on 115 vac 48 to 450 Hz or 28 vdc.

Dimensions: 17-3/8"W x 7"H x 15-3/4"D
