I just blew out my Jeff Rowland Model 201 stereo amp power modules by plugging in the IEC into the amp when the power cable was plugged in.
Make sure the power is off to the power cable before plugging in the IEC to your amp.
Unplugging power cords from amps/ pre amps
This might be a stupid question but when there is a thunderstorm lightning storm I used to unplug my power cords from the outlet but now I can’t do that because of a lot of things in the way to reach my plugs from the outlets. I want to know if it is ok to unplug my amps / pre / cdp from the female end that goes to my equipment and then replugging them back after. Of course the units are off when unplugging / plugging them back. Ty.
