 | | Indiana and Ohio GP7
|
| I've been itching to build an EMD GP7 or GP9 (they are nearly identical in appearance) for a while and I settled on the Indiana and Ohio Railway Company scheme. The air reservoirs on top of the hood aren't (URL) prototypical>, but I just had to use (...) (18 years ago, 21-Aug-07, to lugnet.trains, FTX) !!

| (...) Let me check I understand the theory of this - you want 1.5V across the LED, which means the resistor has to take the other 7.5V. You then pick a resistor that gives you a 20mA current at that figure of 7.5V. Then you double-check the power so (...) (18 years ago, 20-Aug-07, to lugnet.trains)
