This is the schematics of the Mark 2 (analogue 
Simmons ClapTrap), the humaniser is already built in. It was a great idea to use 
the AC frequency from the PSU to modulate the VCO. A free LFO! This is the 
Simmons spirit!
Also bad, that the LM566 (VCO) is so expensive 
these days. Back in the days, you could buy it for a few cents. Now they want 15 
Euro or more.
