Thanks for the MP3 Colin.  It's interesting how the filters in the 606BD 
circuit start clipping against the supply rails when the trigger pulse width 
ventures much above 1ms.

I guess they designed the filters to max out their dynamic range with the 
intended 1ms wide trigger, and they can't cope with the increased energy in 
wider pulses without clipping.
