The range of the tuning knob can be modified by lowering the resistor R5
(1M). If you replace the 1M e.g. by 100k you obtain about a four octaves
range (but then it's more difficult to tune the VCOs). Details in the A-100
service manual (position of R5) and on the A-100 DIY page (chapter 4.1.1.
Changing the sensitivity of manual controls)
