Title: JCM800 clone power switch lamp on low when amp is off, is this normal?
Post by: TubeGeek on August 11, 2016, 12:01:11 am

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.
