1296MHz 600W PA

My last PA project for 1296MHz is still in progress, but I moved to new QTH spring 2019, so everything is on hold for a period of time.
This is the lazy man’s project, as I purchased a complete, but assembled project from Jim W6PQL. My DF9IC project need 4 pcs. MRFE6S9160 to produce 500W. W6PQL use a single PRF13750H which is capable of making 650-700W @8-12W input.
