Xiegu XPA-125B HF + 6 meters: Xiegu XPA 125B Power Amplifier. The amplifier covers 160 meters through 6 meters. It requires a maximum of 5 watts input power to produce up to 100 watts output power. I have used this amplifier with my ICOM 705. It is nice to have extra power when you need it! There is a built-in Antenna Tuner that can handle from 14 ohms to 500 ohms. An external DC power supply is required. Amplifier is in excellent condition.
Asking price is $425.00 or best offer which includes free shipping via USPS Priority Mail in original box and packing. PayPal is fine. Local pickup is preferred in San Diego, CA. I will reduce the price by the shipping costs in that case.
I have an ASTRON RS-20A power supply which can be used to power the amplifier. Let me know if you are interested in also purchasing it.
If you have any questions, please contact me at (858) 357-3856
