I have 4 MRF448 amplifier boards, 100% test OK , 2XMRF448 push pull  in a board, 400W@ 1.8-30MHz,
 It was used in  Chinese SSB 400W transmitter, not for  27MHz or 40MHz RF Power generator.
    I purchase these for about $650 in 2003.But now I do want these, please make an offer. 
You need add control unit  ,LPF,and the 50V power supply, if you put these together, still 
needs combiner etc.
