Summary

Three devices:
Device 1. MC1530 - Motorola, Operational Amplifier designed for use as a summing amplifer, integrator, or amplifier with operating characteristics as a function of the external feedback components.
Device 2. ua727 - Fairchild,Temperature controlled differential preamplifier, mounted in a high thermal resistance package, and held at constant temperature by active regulator circuitry. The device is intended for use as a self-contained input stage in very low drift DC amplifiers in such applications as thermo-couple bridges, strain-gauge transducers and A/D converters.
Device 3. TAA380 - (unknown) Television sound intermediate frequency amplifier

Physical Description

All devices: small metal can with ten wires protruding from the base
