Optional Fixes for the Kiwi-3P
The following are optional modifications that can be made. The first changes the way the LEDs are powered which will reduce the flickering that occurs as LED are changed
on the display. This is more noticeable once the Kiwitechnics 3P Matrix Upgrade is fitted due to the enhanced use of the LEDs.
Step 1 Remove the front panel board. To do this it will be necessary to remove the Jack board to
allow access to the mounting screws for the front panel. This is done by removing the four
screws on the rear of the 3P. The front panel can then be removed by removing the slider
knobs and then undoing the mounting screws.
Step 2 Remove all of the nine 100R resistors identified with arrows. The photo shows these already
removed.
Step 3 Place a link in place of R84 which is identified by the yellow arrow and fit the eight supplied
220R resistors to the eight green arrow locations. There is a resistor numbering error in the
service manual so use the photo as your guide.
Step 4 Replace the front panel board, the rear jack board and front panel knobs
The second modification improves the stability of the Sens slider. On our test JX-3P we had noise issues with
the Sens pot which caused it to be noise prone and jumpy. This can be improved by fitting the supplied 0.1uF
cap to ground on the junction between the Sens Edit Pot slider connection and R95. This is most easily fitted
on the underside of the front panel board as shown in the photo. The Sens Pot is located near the center of
the front panel board and has the word 'EDIT' next to it.
