It may take some searching but try these three ways:
Get in to your local Radio Shack when they aren't busy and talk to the staff. Most of the staff there have a personal interest in electronics and if you get lucky, you'll find one that may have information to help you.
Next, try telephone calls and emails to RCA. Even if they only release circuit diagrams to dealers, you might be able to talk to someone who can let you know the values of the resistors you are after.
Finally, find a forum that discusses electronic repairs and equipment. Get the right forum and there will be someone who may have detailed knowledge of the product.
Happy hunting.

Wiring schematic
Colour code used to identify resistance of the resistor
How do I find out the value of Lalique swan purchased in 1978
Alaska - Purchased from Russia Hawaii Florida Louisiana purchase - Purchased from France Gladstone Purchase Texas
The resistor color code use to help to identify the resistance of the resistor. There are four color in the resistor that help to identify the resistance of the resistor. The first and second color represent the numerical value of the resistor. The third color represent the multiplier. The four color represent the tolerance.
Without knowing the type of transformer (audio/power, step-up, step-down, etc.) it's difficult to offer any advice.
hariram very poor boy and middle class family. i love pathmappriya.
Resistors are color coded to denote the value of the resistor as well as the multiplier. In your case a 470 ohm would be colored as Yellow Violet Brown corresponding to 4, 7 and a multiplier of 10^1.
I would replace them all... you will use a "wiring schematic" to identify the faulty patch cables.

Technically, you consult the circuit card's schematic diagram, identify the failed component using the data you collect by measuring voltages at several points on the card, and you replace the failed component. In the real world of 2009, you put away your voltmeter and replace the circuit card.
