The Set: Pete Deksnis's Site about the CT-100
Restoring a Vintage Color Television Set
CT-100 caretakers who generously contribute the serial numbers of their wards to the Living CT-100 list sometimes are unaware of the location of the numbers.
YELLOW in the upper right circles the embossed cabinet and lid serial number. The third cabinet serial number (hopefully, one that matches the others, indicating a factory-original configuration) is found behind the wood insert under the pencil box on the front of the cabinet.
Check the locale of serial numbers, ballast resistor, and factory lead-dress.
RED surrounds the back of the rectifier cage where the octal-base ballast resistor assembly hangs over the hefty power transformer.
BLUISH (cyan) outline snakes around the yoke-cable shown here with its factory-correct lead dress terminating in another octal base that plugs into the lower right of the high-voltage cage.
GREEN encircles a rivited-to-the-CTC2-chassis candohm resistor that (occasionally) hides part of the CTC2 chassis serial number located just below the venerable resistor.
