TE Systems 4412G power amp, with manual. Rated 15~20 in, 100W out. Specs as measured by TE, when shipped: 15W in, 140W out, drawing 26 amps @ 13.8 volts. Purchased May 2009. Worked well for me. I now own a IC 9100 and do not need a PA. $300 firm. I will ship UPS anywhere in the contiguous 48 states for $17. -- Buddy WB4OMG EL 98
