Default LED on Zen V4

Can anyone give me some idea on how to incorporate a LED in the Zen V4? I just want to have a LED on/off indicator.

Thanks

This info should be available if searched. On mine the two diodes are connected to the last cap in the raw supply. Used a 3.5 volt, 20 ma max Super Blue. Since the rails are 53.5 volts in the amp, a 2500 ohm resistor was used on each side of the diode to limit the current to 10 ma.
It is plenty bright, and works as a bleeder for the filter caps. Due to how the voltage regulator works in the input of the amp, the caps will hold a charge without the led.

Good Luck,
George
