5 color band resistor question hey all i have a resistor in an old silver tone twin twelve that is ginving me trouble, the color code is black, red or orange, grey, blue, and silver. i know that this should be 38 or 28 depending on the red or orange stripe Mohm, but just to check i reversed and used a value to color calc and it came out differant. also i tested the resistor and it has floated to 108k can that be right can it float that much. thank you dan |

| jason | Weird, I've never seen black used as the first band, they usually make the multiplier band black for two digit numbers (28 would be red, grey, black then the tolerance band). Sorry I could be of any real help. jason |

This sounds all wrong. 28 Meg is a VERY high value, I can't recall running into anything over 10 meg in my 50 years on the bench. ANything is possible. FOur stripe codes are common enough today, but back when Silvertone was making amps they were not. Neither 28 nor 38 are on the standard value list. That seems odd too. If you want to measure it, pull it out of circuit - unhook one end. With all the other stuff in a circuit, you cant get a good reading of something that high. Now measure it. Where is this resistor in the circuit? |
