       Grant-XL (8719 PLL) Clarifier Modification
       1. Find D52, R44 and R174 and remove them.
       2. Solder a jumper from where you removed R174
       3. Follow the WHITE WIRE from the clarifier control to where it
       attatches to the PC board and UNSOLDER it.
       4. Resolder this WHITE WIRE to the PC board ground.
       5. Follow the ORANGE WIRE from the clarifier control to where it
       attatches to the PC board and UNSOLDER it.
       6. Resolder this ORANGE WIRE to pin 3 of MB3756 Regulator.
       NOTE:
       Some radios have different colored wires on the clarifier
       control. They are:
       YELLOW instead of ORANGE
       RED instead of BLUE
       If all goes well, you should slide about 4 down and 1 up.
       WANT MORE SLIDE?
       1. Remove D51 and put in a jumper.
       2. Install a "super-diode" in place of the stock varactor D35
       3. Add a 4.7uh to 10uh choke to the banded-end of the stock
       varactor.
