This module is a PCB 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 printed; this module does not have a serial number or a letter suffix appended to the 'other number.'

Opposite the handle there are 47 bifurcated gold-plated contacts arranged in two rows. Mounted on the component side of the PCB are the active and passive components, consisting mainly of transistors, diodes, resistors, capacitors, and jumpers. Two linear trim potentiometers also mounted on the board. Two of the transistors have circular clip-on heat sinks, and two of the transistors are power transistors mounted on their own anodized aluminum heat sinks.

The card has various quality control stamps on one or both sides of the PCB.
