Yes, but only because I used the switch combinations as inputs to a 
solid-state controller...Bob

So now you have 7 micro-switch combinations.  Was there ANY change in the 
number of actual forward speeds?

Bill,
On my E12 the speed lever had a thin steel plate spot welded in a position 
to block the top four speeds, I just chiseled this plate off.  All the 
switches for seven speeds were there.  GE musta used the same speed 
control lever assembly on all the models.

The problem with increasing the resistance of the starting resistors is 
that they waste a lot of power and you'd have poor speed regulation with 
respect to load...Bob

Bob Murcek,
Thanks for your suggestion on Fine Control. But I don't understand it.
    Did you actually make 7 electrical speeds on your ET? If so, how did 
you make
cams to actuate the 7 micro switches? Or did you modify the existing cams? 
Or are
there un-used cam ridges in the ET which you used?
    Maybe a simple fix for me would be to just make the low speed resistor 
(R1) a
higher resistance. That would make the first speed slower and not effect 
anything
else.
