A vintage electronic circuit board primarily acting as a custom resistor-transistor network or discrete component module. Measures 1.5 x 2.25 inches.

Component Breakdown

• Carbon Composition Resistors: The brown cylindrical components arranged in two long vertical columns. They feature standard color-coding bands (Brown, Black, Red, Gold) which indicate a resistance value of 1,000 ohms (1 kΩ) with a ±5% tolerance rating.

• Transistor / Diode Module: The distinct, small metallic rectangular component positioned near the right-middle section. It serves as the active switching or amplifying element in the network.

• Printed Circuit Board (PCB): A classic single-layer translucent yellow fiberglass laminate featuring a single row of exposed contact pins along the left margin for modular backplane connections.
