A-Diode Board

This document is a technical schematic for a diode board. It illustrates a large grid of diodes organized into two main groups (labeled X and Y) with associated connection terminals. Key specifications noted on the document include:

• Components: The primary components are D672 diodes, with D671 designated as a valid substitute.
• Resistor: There is a thermistor (R1) with a value of 330 ohms at 25°C (part number 209058-8).
• Layout: The board features a dense array of diodes arranged in columns and rows, terminating in various connection points labeled with alphabetic designators (e.g., AC, AD, AE, etc.).
