Changing Tubes

 

Power Tubes

1) Grip the base of the power tube with your finger tips, and cup the glass top with the palm of your hand.
2) Gently start removing the tube in a circular (clockwise) motion.
3) Do it carefully as to not to damage or break the tube.

Preamp Tubes

1) Carefully twist off the preamp covers.  It's common to break a preamp during this step.
2) Gently start removing the tube in a circular (clockwise) motion.
3) Do it carefully as to not to damage or break the tube.

Simple as a pentatonic scale!  Fight the urge to use an amp tech, a common misconception about changing tubes.
