Hello everyone, How do I tell the difference between the 120 ohm and 10k ohm resistors seeing as they are both brown, black, black, red, brown? Also, on the rotary switch there are 4 plastic things that hold the two pieces of the switch together. Two of these broke off, and I was wondering if this is supposed to happen? Do I need to take off the plastic tabs to use the rotary switch? Thank you!
