Nice job with the video. Having built plenty of shunt fed (gamma match) 
systems, I found your info confirming very nicely all of my “cut and tried” 
methods with the added advantage of using much nicer tools. 

I own the AA-55 Zoom as well and love it for this kind of work. 

Thanks again!

Mark, K1RX
