Right!
We have enough people using MA-1s with the Sound Lab to know that they do work :) Doing the mod really helps them out
The big increments on the graph are 5 ohms. You can see on the left that the scale goes from double digits down to one single, and Roger mentioned something to me about a 40 ohm peak, which does correspond to the graph. That puts the minimum impedance of the bass transformer at about 7 ohms. The far right side of the chart appears to be 20KHz. I suspect that with all the other mods (not just the resistor) that 1.5-2 ohm value comes up a little.
