Tokyo Hy-Power HL-770B Solid state 500W Linear Amplifier. The excellence in quality continues with the release of the Tokyo Hy-Power HL-770B With a rated output power of 500W and the all solid state FET design, this amplifier is sure to me the needs of even the most avid DX’er.
This amplifier requires the soon to be released HP-770 100amp power supply, or another 13.8V source rated to 100amps.
A compact solid-state linear to boost 60~100W exciter to 550W PEP (typ.) output on HF band, making full use of the latest semiconductor circuit technology.
Built-in auto band-select function that uses a newly developed micro processor based technology, and works a smooth automatic operation when driven by the radio. ( Manual band setting is possible as well. )
The HL-770B is capable of turning ON / OFF the optional DC power supply HP-770.
The HL-770B is equipped with a hard-key terminal to make a smooth send / receive switching with the radio, and also an output terminal for ALC circuit which controls the output of the radio. ALC helps suppress excessive
output and avoid the signal distortion.
The HL-770B has various protection circuits such as for high antenna SWR, over-drive, over-voltage, band mis-set, over-temperature, and PA unbalance. When any abnormal condition is detected, operation is automatically
shut down to prevent the failure.
With the large analog multi meter, Pf ( transmission power ), Pr ( reflected power ), and V DC ( power voltage ) can always be monitored.
RF key is available, when internal switch is selected.
