brown and orange do look alike with the paints lots of the
manufacturers use, ESPECIALLY when they are not viewed side-by-side.

Glad you got it working!

Yep, that old color code can be troublesome. Now that I think about it,
wouldn't the last value stripe on a 180K be yellow? Unless we're talking
precision (1%, 4 stripe) resistors, in which case it would be orange all
right, but then the 180 ohm would end in black.

A charitable offer, but I don't think this was a case of color confusion.
