Does anyone know who can supply the gas discharge display unit/units in the NARCO MK12D nav/com?
 
My display is failing hard to se at night , not so bad by day, but has to be fixed.
 
I see lots of adverts for the MK12D+ upgrade, but would like to start by trying to repair or replace the display panel.
 
Or buy a second hand unit which I guess can have same problems.
 
Does anyoen have a link to the repqir manual for the MK12D or part numbers for the front panel displays?
 
Thanks
