Blanking Resistor
Some
2600A PCBs have an 820
1/4 W 5% resistor (P/N 14-5821) installed on the
solder side (bottom). The resistor is located between pins
6 and 9 of A201 (TIA) and
improves the color reproduction of the unit.
The resistor may be added to existing
2600A units at your discretion and the
customer's expense. The addition will result in improved color saturation.
Rev.
16 PCBs and above will have the resistor incorporated into their design.
