Write to us for details. All other units DO NOT require a kit, only the following written instructions. AL-80A To obtain 10/12 meters on your AL-80A, cut the green wire that exits the subchassis at the front panel end of the bandswitch. This wire connects to the ground lug under the top mounting screw of the plate tuning capacitor reduction drive. AL-80B / AL-811 / AL-811H / AL-572 To modify these amplifiers for 10/12 meter use follow these steps: 1. Remove the top. Locate the Rear Panel P.C. Board. 2. Locate the green wire that is connected from the P.C. board to one of the coils as depicted in the diagram below. Cut the green wire. 3. Replace the top. NOTE: Input Circuit Tuning. If high SWR occurs at the input of the amplifier, adjust the tunc-input circuit with a 0.1 inch hex T.V. Tuning Tool, Adjust the slug for low SWR when the amplifier is transmitting and tuned properly. 20M 80M Input Coil Input Coil PCB Switch 160M 10M Input Coll Input Coll Cut this Green Wire O 40M 15M Input Coil Input Coil AL-80B/AL811/ AL811H Rear Panel PC Board AL-82 / AL-1200 / AL-1500 To obtain 10/12 meters on your AL-82, AL-1200, or AL-1500 cut the green wire at the front of the band switch, AL-800 / AL-800H 1. Place the amplifier onto a level surface so the back is easily accessible. 2. Locate the cover that is marked INPUT TUNING on the back of the amplifier. 3. Remove the four screws that secures the cover to the back panel. 4. Remove the cover from the back panel to expose the tune input circuit. 5. Locate the green wire that is solder to the PC board. 6. Remove the wire by either; un-soldering or using a pair of wire cutters. Cut the wire short enough so the end will not shift and short against anything. (It may be necessary to remove the wire at both ends.) 7. Replace the cover back onto the amplifier and secure the screws. The amplifier is now modified for 10/12 Meters. Use the AUX position on the Band Switch for 10/12 Meter operation,
