Elecraft KXPA100 100W amplifier with internal ATU. Specs and photos at:

This is a 5W in, 100W out, 160-6m amplifier designed to interface with the Elecraft KX3 or KX2 portable QRP transceivers. Bought new a couple of years ago, factory assembled direct from Elecraft and cost me over $1200 including all necessary interface cables and manual. Works perfectly, I just find myself using the rig QRP more often. Can interface to other QRP rigs such as the FT-817 with a keying line, see manual. 
 
This has the great internal ATU with additional antenna jack and can generally match loads up to 10:1 SWR, much higher than your normal rig’s internal ATU.
 
Utilitarian brick amplifier shape, 20A at 13.8VDC required; NO COOLING FAN needed because of the large heatsink, totally silent operation and QSK.
 
Price $999 firm, a bargain, local pickup in Chelmsford or can deliver a reasonable distance. Email me direct, soldersmoke01 at gmail.com
