After closely scrutinizing the board, I noticed that there are numerous
resistors similar to this burned on. I pulled one of them out of
circuit. The colors of the unburned ones are:
brown, black, black, orange, brown The orange had charred to a brown.
That explains why it was a little darker of brown than the brown
stripes. It measured 100.4k ohms out of circuit, so I believe this is
the jasper that I'm looking for. I couldn't figure why a 1k would need a
1 % tolerance, but a hundred thousand would make some sense. Thanks for
the input guys.
