TE systems 1452G 2M Amplifier with working preamp. Comes with keying cable and copy of manual. I have been using it at around 15W drive for 300W out. It is advertised as 350W out but too much drive will damage the driver transistor. If you have a rig capable of adjustable drive this will work for you, I use transverters with adjustment capability. Preamp works great. I just went to a bit larger amp with separate preamp. $475 shipped USA only Paypal preferred for payment but USPS M.O. accepted, ship when M.O. received. New they are $698 on TE Systems website.
