Coil forms for the GW3UEP 630 meter power amplifier

These are forms for winding the three coils used in the 630 meter power amplifier for amateur radio that was designed by GW3UEP. There are two mounting clips to put L2 and L3 horizontal. It is important that the three coils are not parallel to each other to avoid interaction between them. The normal configuration is for L1 to be vertical with L2 and L3 horizontal and at right angles to one another.
