Keeley Tube Drive - Harmonic Distortion and a tube swap!
We study the distortion content and makeup of our Tube Drive with different tubes! We compare the harmonic content (even and odd ordered harmonics) and then I show how easy it is to swap the tube out for a different variety! We test a 12AX7, 12AT7, and lastly and 12AU7. Testing done in my trusty Audio Precision APx515.
