The coils are very difficult to de-solder, Dave places the assembly on and electric kitchen stove at the lowest heat setting. He does not get it hot enough to melt the solder but uses his solder gun to remove and replace the coils. I use a butane torch.

Remove the covers from the receiver rf assembly. Be sure not to mix you screws when replacing cover.

Note the location of the coax connections to the coils and remove the connection. Solder wick works well. When you replace the coax connections, replace them 1/8 turn closer to the soldered end of coils

The RF Assembly has 2 enamel coils and 5 silver coils. Coils L301/311/C301 and L305/315/C305 have taps on the bottom turns. Both taps were originally placed directly across from the solder ends of the coils. Dave replaced both taps 1/8 turn closer to the soldered end of the coil

After removing the turns, pull on the top and bottom of the coils until they are at the original length. When you replace the coils, the bottom should be just touching.
