U18747 Used Neptune 50W HF/6m Auto Band Switching Amplifier

U18747 Used Neptune 50W HF/6m Auto Band Switching Amplifier

Perfect for 

Yaesu FT-817, Icom IC-703/705, Elecraft KX3, automatic band switching

This amp is in great shape. Some of the heat sink fins are slightly bent and there are some very small scuffs, but this unit is super nice all around and works great. The text is good, the cord is very good, and the powerpole connections are sturdy. This unit comes with no accessories other than the guide but makes for a great buy!

Caution, This amp has a 5 watt maximum input. We will not warranty for blown finals due to being overdriven

This is custom designed HF/6M solid state ham radio amplifier with automatically switched LPF onboard, 4 x RD16HHF1 based, intended for field or mobile operations or as driver for LDMOS amplifier. This amplifier produced from high quality ORIGINAL parts, such as Mitsubishi transistors and AMIDON cores. PA PCB mounted on metal heatsink for good heat dissipation.  PA has 3 dB flatness of frequency response and PA can operate 24x7x365 in any digital modes without extra cooling.
