Object is a PCB with a handle for extraction. It bears 10 discrete transistors and other components including 6 screw-adjust resistors. Printed on the component side is "OPERATIONAL AMPLIFIER" and copyright SDS-62. On the solder side is one round and one square inspection stamp. This module differs from its litter-mate (102730800) with design 100640F, in that four of the transistors are of a different type and mounted in small heat-sink clips.
