The linear amplifier HF2013DX-A is designed for all shortwave bands from 1.8MHz to 29.7MHz amateur (including WARC) and all operating modes. It is equipped with a ceramic tetrode FU728F (4CX1500B). HF2013DX is version manual. The amplifier compared to other similar products and powered with two distinct power supply (two phases) to avoid voltage drops, maintaining a lower cost compared to the competition which use a single transformer. All this makes it suitable for use in extreme conditions type Contest.  For the price and the possible purchase refer to the website of our e-commerce at the following LINK
