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-A is automatically tuned to the frequency of operation of your TRX when connected properly with the right control cable. 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 coinditions type Contest.  For the price and the possible purchase refer to the website of our e-commerce at the following LINK
