Ask your local transformer manufacturer how much to make five of these and see what they charge you!!

Re manufactured Narco 11937-1 / 11937-0001

Switch mode power supply (SMPS) transformer.

Same part is used in the MK-12D, MK-12D+, COM-810, COM-811, NAV-825, 14 Volt or 28 Volt units.


I was lucky enough to have a new original part, this was copied by a UK transformer manufacturer with the brief "Improve it".

I gave them a burnt out part so they could see the weakness.

The last picture is of an original part, this is just so you can compare them together. This is not what you are bidding for!

Narco ceased trading around April 2011.

A Google search shows a couple of USA shops have them, when you

e-mail them, they don't!

The same XFMR fits 14V & 28V units.

Most common they fail in the MK-12D / MK-12D+ units due the extra power consumed by the larger display.

The 198 Volt winding burns up.


The OEM price from 2011 $150.64!

With the normal year on year price rise that would now be $190.
