Step 1: Remove the filter from the main casting by removing 4 screws.

Step 2: Remove the cover to the harmonic filter by removing the 2 screws on the rear of the unit.

Step 3: Remove 1 turn from the center of each coil, and solder the 2 ends back together. Stretch the coils to their original length and fine tune length for minimum VSWR. (See Fig. 7)

Step 4: Re-assemble and re-install filter assembly in Radio.

The Radio should make 25-30 watts output and the power control board should work exactly as it did with the original PA.
