Mil-Spec Green Phosphor:
These are sealed in canister Photonis ECHO Mil-Spec grade green phosphor auto-gated 1500-1800 FOM tubes with manual gain control (MX-11769 format). Colloquially known as FMS - For Foreign Mil Sale. We were fortunate enough to be offered these tubes by Photonis Defense as part of a new overstock. They are factory new sealed in canister and come with a data sheet and factory warranty. These Photonis ECHO tubes can be converted to 10160 format as well via external gain adjustment controller removal - while still maintaining their factory warranty.

These are factory new Photonis ECHO white phosphor auto-gated 1800-2200 FOM tubes with manual gain control (MX-11769 format). These are new unused tubes and come with factory data sheet and warranty. These Photonis ECHO tubes can be converted to 10160 format as well via external gain adjustment controller removal - while still maintaining their factory warranty.
Image tube sales are final. These are a factory Photonis product. We do not manufacture image tubes.
