Schematic diagram

Air coils:

• Wire diameter = 0.8 mm

• Diameter pen = 9.7 mm
  

L1 = 2 turns L2 = 3 turns L3 = 5 turns L4 = 7 turns L5 = 12 turns

Other coils:

L6 = 18 turns on a T50 - 2 (red) core Amidon

L7 = 28 turns on a T68 - 2 (red) core Amidon

Capacitors are SMD 0805 type see pictures for detail.

For tuner 2 I replaced C5 (220pF) with 180 pf to make tuning easier.

For tuner 2 I replaced L7 (28 turns) with 26 to make tuning easier
