    I can send you all the information (+ photos) on a || 4CX250B rig. It uses the Russian version of the 4CX250B. My amp uses two tubes and puts out ~600W with a puny power supply. My best DX is 1200 miles. If you are halfway handy this is an easy rig to build in a month of spare time. This is the famous W2GN design that was sold commercially for a while. Reply at melandjohn@netsync.net & I will get the stuff out to you.
