I have the stuff to make it, and plan on doing so..... I have some of that same material, I can cut it with a box cutter and a ruler. I can't cut straight with scissors. I used a box cutter, file and a pin vice to make the top connector for the plate choke. I have thought about pushing the fan blade further back, it was a tight fit on the new motor shaft. The amplifier tests okay after the new choke installation. I did notice I have an input VSWR issue on ten meters. Power is down on ten as well. I'll address that the next time I open up Oscar.
