The AGM MX-11769 NL1 is an 18 mm Gen 2+ image intensifier tube with a green P43 phosphor and manual gain control (MVG). The manufacturer designates it for AGM night vision devices in the PVS-14, NVG-40, NVG-50, and UNVG families, making it ideal for servicing, tube replacement, or building a device using an SKD housing. A resolution of 60–64 lp/mm and a figure of merit (FOM) of 1350–1450 at a signal-to-noise ratio of 23–25 provide a clear image in low ambient light.

Compatibility
According to the manufacturer, the tube fits all versions of AGM PVS-14, PVS-14L, PVS-14E, and PVS14-51 night vision devices, as well as NVG-40, NVG-50, and UNVG goggles—for example, the AGM PVS-14 NL1. The tube may have contacts in the form of wires or pin headers, so it is worth confirming the correct version for your housing before ordering. The tube should be replaced when the existing one is damaged or worn out, or when you are assembling a night vision device from an SKD housing without a tube.

Frequently Asked Questions
Does this tube fit AGM PVS-7 goggles?
The manufacturer does not list the PVS-7 among the devices compatible with the 11769-type tube. For the AGM PVS-7, the manufacturer specifies 10130-type tubes, such as the MX-10130 NL1.
Does the tube have an autogating function?
No. The power supply for this version operates without autogating, and the gain is adjusted manually (MVG).
Can I install the tube myself?
Installing the tube requires experience, so it is best to entrust it to a service center or someone who has assembled night vision devices before. We recommend contacting us before purchase to select the correct tube for your device.
