The 750 would most likely work, but you can put two resistors in series that add up to 760 ohms. also you can measure the 750 ohm ones until you find one that is close to 760 ohms.Can any body tell me where to find 760 ohm resistors. It's the only part I can't find. Would a 750 ohm work? Thanks for all the info I'm looking forward to building this
Remember the value is plus or minus 750 ohms based on the tolerance of the resistor. So if you have a 750 1/2w +-5% resistor it could be as low as 712.5 ohms or as high as 787.5 ohms.
