Nice information.=20
I never got to hook my Continentals up to a scope to have a good look at th=

em but I agree the sines were not all that pure so a tri would be possibly =

closer to the original than a sine waveformed lookup table as used by Conni=

e. I might actually give this a test in bristol and see how its Vox sounds =

with them=2C it also uses similar lookup tables. It would not be that diffi=

cult to fill them with heavily RC filtered square waves=2C even testing wit=

h some different slew rates and see what effect that has.
Your comments on the drawbar effects are very interesting=2C I had never co=

nsidered the Vox to have damping as the Hammond did but I would definately =

believe it. Do you happen to know if the schematics were from a Mark-I Jenn=

ings design? I would be interested in modeling some of the resistor circuit=

s as well.
