I'm search for a missing display button for a Harman/Kardon A-402 stereo amplifier. Note the missing "2" button in the bottom of the black VU/level display, just below the "Display Sensitivity" label.

If you have a button to sell, or even the whole display panel from a Harman/Kardon A-402 or Citation 19, please email dave@armchair.mb.ca
The exact dimensions and appearance of the button are shown below.
