Silly question but it's the first time I have noticed this.  I just finished building a mojo jcm800 kit and when the amp is plugged into the wall AC, I notice the power rocker switch lamp is on low in the OFF position.  It lights up normal when I turn the switch to the ON position.


Is this normal?


I haven't noticed this before.

I don't think that's normal. Looks like the switch is bad.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
