HF Linear Amplifier
DXV500L
(Discontinued models)
NEW MODEL : DXV500Z
This is the minimum in the world completely made from the new kind of thinking and linear an amplifier.
We chose the FFT of high voltage as the amplification part, and it made the power transformer unneccessory.
The performance is minimum size, lightest weight in the world, high-power, high efficiency and low-priced.
You can put this in the suitcase, go to the southern island, and operate real DX pedition (but only low bands hihi) during the vacation.
Moreover, please use it as the 2nd and 3rd linear amplifier.
