Commander HF 2500 HF AMPLIFIER: Hi Up for sale my Pat Stein Command technologies HF 2500..If you have been a ham for 10 years or so, You know what this amp is capable of. It's one of the best HF amps made,
This is the one you have been looking for as it's a tank....
it weighs in at approx 78 lbs, will only work on 240 Vac and works fantastic. with as little as 20-25 watts drive will deliver legal limit as per the LP-100A. This amp has two Eimac 3cpx800a7s these are the Pulse rated MRI medical triodes. I also have an extra set of Eimac metal ceramic tubes as back ups but have not needed them as the amp does full power out and then some. I have seen 2.9KW while testing into a dummy load using a pecker. The meter lites have been upgraded to defused white leds . You must come to pick it up or arrange shipping... it's in great shape and the last amp you will ever need. I never push this baby, I always keep it just loafing near legal limit as my antenna only will handle legal limit.. 2500 and it's yours.; Listing #1749378 - Submitted on 11/13/25 by Callsign W8NVC, Modified on 11/13/25 - IP: ip174-66-201-198.cl.ri.cox.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

Elecraft KPA1500 amplifier: I have for sale my Elecraft KPA1500 amplifier. I bought it along with my K4D but have not used the kpa1500 because I do not have 220v in the shack. The amp and radio was purchased from an elderly ham and he used the set only occasionally. I am happy with my Mercury Lux and Lite amps so going to sell the KPA1500. The amp comes with all original packaging items and cables.
