[Amps] AIR-DUX coil info wanted

[Karl-Arne Markström]

According to information in an old ARRL Handbook
an Air-Dux 195-2 coil assembly consists of these parts connected in series:

L1, strap coil for 10 m, 4 turns of 5/16" width strap, 1 1/2" diameter, 2 tpi

L2, tubing coil for 15 and 20 m, 4 turns of 1/4" o.d. tubing, 3 " diameter, 2 tpi. Tap for 15 m bandswitch posn 1 3/4 turns from L1 end.

L3, solid wire coil for remaining bands, 16 turns of no 8 wire, 3 1/4 " diameter, 4 tpi. Tap for 40 m bandswitch posn 7 turns from L2 end.

Hope this helps & 73/
