Known Issues
Knob is Gone
Causes
- A big whack
Solutions
- Replace potentiometer, hopefully find knob
Buttons Stuck Inside
Causes
- Rushed reassembly
- Depressed in too far
Solutions
- Open device, remove button panel, re-apply double sided tape to secure buttons and replace them, reassemble
Disassembly Notes
Be sure to remove knobs, slider caps, rotary wheel, and nut under rotary wheel when removing top panel
Clear faceplate over LCD is double sided taped on top and bottom. Use a thin guitar pick to break glue loose from inside and then work it slowly from the front once raised. Warning: the tinted covers over 7 segment displays can be scratched

If parts are not available or different selection is preferred, you can use the values in the Original Parts section to perform a parametric search.
Note: It seems detented potentiometers are not being made or are extremely difficult to find. The provided part number is from the P09x datasheet[1] that should be detented but there are no good sources available. A non-detented model could be substituted without issue.
