Should I use an amp tech to change tubes? No!

Common misconception when replacing tubes

Changing preamp tubes is easy and can be done by the newest of newbies.

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. (Its common to break a preamp by taking the cover off to harshly).
2) Gently start removing the tube in a circular (clockwise) motion.
3) Do it carefully as to not to damage or break the tube.



The only tech related tube issue one might have is re-biasing the amp.


Even this isn't TOO hard to learn, however it is recommended that one do HEAVY research and Q & A before attempting. You could damage the equipment, or more importantly, yourself.
