Coil forms for the GW3UEP 630 meter power amplifier

thingiverse

Forms for winding three coils used in the 630 meter power amplifier, designed by GW3UEP, are listed here. Two mounting clips secure L2 and L3 horizontally. It is crucial that the coils do not line up with each other to prevent interaction between them. The standard setup features L1 standing upright while L2 and L3 lie flat at a right angle to one another.
