components are generally marked as to their circuit. The operation and features of the "TX" chassis is similar to the "CTC"
series chassis. However the component numbering system is slightly different than in the past. The component numbering for
G1 Gemstar (21146070) the "TX" chassis reflects the component's type and use as to the general circuit areas it is used. The component labeling

SCHEMATIC NOTES
1. Resistor values are in ohms (R = 1, K = X1,000; Meg = X1,000,000). Tolerance is 5%, unless otherwise specified.
Example: 1R5 = 1.5 ohm, 270R = 270 ohm, 2K7 = 2700 ohm, 1M5 = 1500000 ohm
2. Capacitor values 1.0 and above are in picofarads; values less than 1.0 are in
