Greetings, I have a friend who was looking for a cable # CG-764. From my brief search It seems to be a connecting cable from a BC-614 speech amp to the BC-610 Transmitter. Anyone have one? Am I correct in it's use? John Flood TASC Department KROHNE, Inc 7 Dearborn Rd. Peabody, MA 01960 Tel.: 978-535-6060 / 800-356-9464 Fax: 978-535-8180
