 Elecraft KPA-1500 Amplifier  
Amazingly, I ended up with two of these, via an auction - selling this one. Very nice shape. Very little use. 160-6m. 1500 watts with included separate power supply. I tested in my shack and all seems to be working fine. Very good cosmetic condition, just some dust here and there. A few minor smudges, as well. Includes hi-voltage cable to connect power supply to amp and the 220v cable. No other cables included - just what is shown. Manual is online. More pictures available. I will consider shipping, but it would be additional cost for buyer and somewhat pricey with two heavy boxes. Price FOB Rockford, MI: $4875.00
