Tokyo Hy-Power HL-510V VHF 500W Amplifier

HL-510V is a solid-state VHF/144MHz band linear power amplifier with the maximum output power of 500W. Switching type AC to DC power supply is built in. It is great for 2m DX communications as well as EME QSO.

Built in super low noise RX preamp.

AC voltage is automatically selected between AC 100V and 240V. No rewiring of AC primary voltage is required, if you change operating AC line voltage. Only the AC plug change is needed to fit your particular operating location.


A pair of the latest RF MOS FET, MRF151G's, designed by Motorola, are used at the power amp stage to achieve a stable output of 500W max. Broad band design has eliminated the troublesome tuning operation as is needed with a tube type linear amplifier. Turn the AC power switch and you will be on the air. With the ducf structure for cooling air flow, an ideal cooling effect has been achieved.

RF key circuitry is built in. When the RF driving power is detected, the amp will be automatically keyed. Also the STBY (stand-by) terminal is located at the rear panel with which the amp is keyed through the radio.

Various protection circuits have been built in such as for power supply, antenna, RF power amp board etc.

A large analog meter monitors the forward and reflected power always.
