NOTE: Anytime you want to substitute a different tube than what your tube amplifier calls for, do some research first, check the data sheets and proceed at your own risk! Some positions will not work well, an example of this is a Phono Preamp, the EQ circuit is often linked to these tubes and a 12AT7 may change the sound!
