Be Careful w/ R30, R33, & R37!

[ghetto3jon]

i've done three T15s, and i've noticed something strange every time:

R30 and R33 are "Brown, Red, Black, Black, Brown." R37 is "Brown, Black, Black, Red, Brown." so they are the same colors, but they are not the same value. R30 and R33 are "120," and R37 is "10k0." so you must meter them to be sure you put them in the right place...just reading the colors is not enough in this case.

i don't know what would happen if they were put in the wrong place...maybe nothing. but i'd thought i'd say something anyway.

No BOM error, this is just one of those values that reads the same in both directions. The tolerance band should be separated from the rest of the bands by a bigger space, but sometimes it's hard to tell. If it's not obvious which direction to read the bands, you'll have to measure the resistor with your meter. In this case, you'll have very weird power supply voltages if a 10K is substituted for one of the 120 ohm parts.

gotcha. thanks, tim.

i meter every resister every time, so i didn't have a problem. i just wanted to point it out because it is something that i can see being a problem is someone is not paying attention.
