LED for BrianGT 3875 Kit

dsavitsk · 26th February 2005, 09:10 AM

Can anybody tell me a simple way to add an LED to the rev B kit (short of swapping out the power supply?) I searched all over for this as it seems an obvious thing to do, but I didn't have any luck.

Thanks,

Just take any LED and connect it in series with 2.2-3.9 kohms metal film 0.6W. Put this LED + Resistor and connect it between your supply voltage and ground.

You can also wrap a few turns of wire around the transformer until you have about 3 volts. this separates the LED from your amplifier circuit.

you still want a current limiting resistor thou
