Not sure about the diode, but there will be one in there when I'm done with it. In my big plan, its s spare / learning toy. I have the TNT 350 hd for the base, and a 2 pill AB amp for the mobile. The next amp I'm buying for 10-12 metres will be a texas star 2 pill. Down the road I'm looking at a 1kw tube for the HF rig.
