ameco AC-1, AC-1T Service Manual
INSTRUCTIONS FOR AMECO TRANSMITTER KIT,
1. Check the parts in the kit with the Parts List. Should inspection reveal a missing part, notify the factory in
writing. There should be no shortage of parts since all kits leaving the factory are thoroughly inspected. A
slight difference in value between the actual part and the Parts List does not mean that you have the wrong
part. For instance, the kit may have a 67,000 ohm resistor, while the Parts List calls for a 68,000 ohm
resistor. Both parts will work equally well.

2. Follow the step-By-Step instructions carefully. Double check frequently and do not attempt short cuts. The
instructions have been written so as to complete the kit in the shortest time with the least difficulty.
3. USE A ROSIN CORE SOLDER TO SOLDER ALL CONNECTIONS. Make sure that the soldering iron is properly
tinned, hot, and clean at all times.
