It requires a maximum of 5 watts input power to produce up to 100 watts output power. 100% Solid State. 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.
