The [[Moog ]] 959 X/Y controller consists of two audio taper [[Allen Bradley type J pots|AB type J 10K pots]] and voltage limiting resistors. When centered the pot is at zero volts and travel is about 15° to either side. Care is needed to set it up so that at full swing the power rails are not shorted. The rotational resistance of the pots dictate the feel of the stick. The shafts of the two pots are simply connected by one L bracket.<ref>[http://dropmix.xs4all.nl/pipermail/synth-diy/2016-January/047788.html XY controller build?], SDIY email list, Jan 2016</ref>
