[HBR] HBR-13 with command-set IF coils?

[Chris Howard]

If building with the command-set IF coils,
what would be the procedure on the double-coil
setup in the HBR-13?

I guess I'm seeing T1a, T1b at first IF
and T2a, T2b, T3 and T4 at the second IF.

Drop T2b? or get a another 1st coil
from another command-set?
