Hey, thought I'd help out any confused builders who just received their armstrong twin kit and started building. The parts list shows the resistor color codes for a mix of 4 and 5 bands color codes, but not both. When my kit arrived it contained resistors of only the 5 band color code, but it did contain all the right resistors.
So if you are confused about what you are looking at just check out

Sorry for posting this if it is too obvious, but I figured some builders might be a little more electronically inept than others.
