Considering how easy it is to build a tuner for 160, even a double balanced one for open wire feedline, not sure who would want to butcher a classic tuner and lower the value by 50%. Then again, that happens frequently when you see all the pilot lights, switches, repaints, etc. of vintage gear on Upay. As to the "limited" matching range of the Johnson Matchbox, I've never had a problem in that area. It is indeed hard to determine the matching range of a tuner because the specs generally don't state the matching range or, if they do, they typically only give the resistive component and not the reactive component; it is the latter that is the "gotcha".

Somewhere I have the article. Does require some work and potentially a 12volt supply if you use relays vs switches.
