    I've been putting this off cause I thought it was a dumb question but curiosity has finally gotten to me. When u look though the top at the inside of the this head there r some light yellow LEDs and one red LEDs . Is that right does everyone have that one red LED. Or is something wrong with mine. Are they all suppose to be yellow?

    I believe the red LED indicates that there is still power in the amp. Don't start changing valves or playing around with the head until it has faded completely.
