| Notes | Quad VCA The QUAD VCA uses PC board VCA 101. The dotted lines on the drawing represent strips of masking tape on the rear of the panel. These should be applied before wiring is begun since their purpose is to guard against possible contact between the resistor leads and the panel. The resistors are color-coded with the following codes: 100k: Brown-Black-Yellow-Gold 82k: Gray-Red-Orange-Gold 220k: Red-Red-Yellow-Gold 33k: Orange-Orange-Orange-Gold 1.5k: Brown-Green-Red-Gold |
