Description

These modules are PCBs intended to be inserted in a card cage. There is an extraction handle attached to the front of the card, on which a paper label containing the model number, serial number, and other information is printed.

Opposite the handle there are 47 bifurcated gold-plated contacts arranged in two rows. Mounted on the component side of the PCBs are the active and passive components, consisting mainly of transistors (one clipped into a board-mounted heat sinks), diodes, resistors, capacitors, and jumpers. There are also two linear trim potentiometers mounted on the board. One of the modules has a metal cover mounted over all the components and attached to the board with four threaded stand-offs.

All the cards have various quality control stamps on one or both sides of the PCB.
