New, from the same US-based OEM vendor that supplied Narco when they were still in business. Every avionics-related item I sell is in the spirit of reducing costs for pilots like myself. I've helped over 150 MK12D owners get their displays working again over the last two years. I'm an electrical engineer and Narco Mk12D+ owner too!

If your Narco MK 12-series radio has malfunctioning digits or is getting dim, this is the part that you need for repair. Hard to find, and otherwise very expensive! Replacement with common hand tools takes about 20 minutes, with the superior detailed pictorial instructions I provide. I even furnish the uncommon small tool and spare setscrews!

Each order contains:

1 OEM display, Narco P/N 50401-0001, shipped in anti-static materials and box with ample padding to avoid dislodging internal liquid mercury in transit

Instructions with pictures for inspection and installation (sent as PDF by email after shipment)

1 each hex and spline (Bristol) wrench for knob setscrew removal

4 spare setscrews for knobs, in case you lose or strip any
I ship only fresh datecodes.This is important, as these displays contain a mildly radioactive gas necessary for their operation, which decays with time and impacts the total life of the display. Some of the displays found on ebay are from old inventory. I buy directly from Narco's old supplier, so the displays are right off the production line.

Note that not all Narco display malfunctions are due to the display component itself, such as sudden blackouts, which may trace back to the high voltage power supply used to run the display, or segments persistently stuck on or off across all digits, which trace back to the high voltage display driver components. A typical failure of the display will cause gradual degreadation until some digits or segments are left working sometimes but not others, improving after the radio gets warm, or after being power cycled. A failing display will likely lose significant brightness, even though the dimming function still responds.

I am now selling FAA-traceable parts for the repair of most other display defect issues beside power supply failure--please look at my other Narco parts for sale.

If you do not choose to replace the display yourself, make sure that you choose an FAA-approved repair shop to do so, in order to maintain the radio's airworthiness, and to make sure your radio and the display are handled properly.

Due to the nature of this component, no refunds will be issued for displays that have been installed, or where the glass or pins are in any way bent or broken. Verify your high voltage and failure symptoms first! I encourage dialog and furnishment of pictures showing the display in a working radio.

Displays will be shipped in anti-static material with ample packaging, in a box, to prevent damage and internal displacement of mercury, which will drastically shorten the display's life. Shipping is via USPS Priority or Express in the US, and USPS EMS Express internationally.

Parts will be serialized with a permanent label for easier logging. Certification of Custody, lot number data, and data sheet available on request with purchase.

I ship internationally, and have for 14 years.
