In my audio project that is powered off dual +/-15v rails, I would like to connect a simple LED indicating power on. However, when I connect it with a 1.5k resistor in series (2W), the ~28V dissipated as heat are excessive and the resistor gets very hot (too hot for touching).
What is the best way of dealing with this? Should I use two larger value resistors in parallel with each other so they share the heat? Should I connect it just between + and GND instead of between + and -? Wouldn't that put a imbalance in my rails used mostly for op-amps?
