The HLA 150V is a 12V linear amplifier with a maximum output power of 150W, designed for use on all HF bands from 1.8 to 30 MHz, with a drive power of 1–10W. The HLA 150V features six Low Pass Filters, which are automatically switched by a microprocessor or can be manually selected from the front panel. It also includes an LED power meter, a 3dB input attenuator, and RTX control via either VOX or PTT. The difference between the HLA 150 and the HLA 150V is that the HLA 150V comes equipped with two 80mm fans mounted on the heatsink for improved cooling.
