Tuned pinfoot match:
1. Position number L927 original 3nH cancel
patch, L927 position number blank patch.
2, L913 increases 68nH inductance, and C913
increases 39pf capacitance.
3. R901 adds 12nH inductance (tentative match
here and may be adjusted later). The R902 uses
the 0 Ω connection tuning switch.
