Hello,
Please excuse a basic question, but I am struggling to figure out the value of a resistor based on its color code(!).
As far as I can tell the color rings are silver, black, purple, red and silver (see picture). The color balance in the picture is a bit off, but the middle ring surely is violet (not gray nor blue). The rings at both ends are the same color and have a bit of a metallic sheen to them, so gray is unlikely.
Using my normal color-chart for resistor values, this makes no sense. Can someone help, please?
The circuit is a low noise amplifier. There are two of these resistors, There appears to be one in series with the +12V and one with the -12V supply to the input OP (AD797). However, I could be wrong here.
Thanks in advance!
