Zhong Xing Power Amplifier

Since 2010 with advanced technologies and selected materials, we began to manufacture Zhong Xing Power Amplifiers for global radio amateurs. Now we provide two models: manual HF2013DX and automatic HF2013DX-A. We received favorable comments from our customers after their two-year trials.

Specifications
Frequency	1.8 – 29MHz
SSB output power	2000W
CW output power	1500W
Driving power	5 – 70W

General description of the amplifier:

The linear amplifier the amplifier is designed for all short wave amateur bands from 1.8 till 29
MHz (including WARC ?C bands) and all modes. It is equipped with a ceramic tetrode FU728F=(4CX1500). The amplifieris automatically tuned to operating frequency of your TRX.
