Not to beat a dead horse, I'm used to thinking in terms of AWG and point-to-point. So this is handy for me to know just in my head making PCB's. So took the time to relate trace widths to their approximate AWG in terms of cross sectional area. Thin wire can carry the load of most tube circuits, but this was an eye opener for me as I've never compared traces to wire. Turns out 3oz copper with 3mm traces gets you to the 1960's phrase we've all seen in parts lists "22 gauge hookup wire".
