6L6 Tube
The 6l6 tube was also modeled in the same way as the 12AX7 and the 12AT7. Figure 1 shows the phase inverted output from the circuit simulation.

Again, after eliminating time, the input to output relationship for the 6L6 tube was determined and is pictured in Figure 2.

After fitting a cubic function to the line, we wrote the Matlab function pictured in Figure 3.

Below is an example of how the 6L6 simulation sounds.
In general, the analysis of previous tubes covers the accuracy of this tube, but we are still pretty happy with the warm distortion and volume difference that we got out of the tube simulations.
