Conrac Schematic

[Findm-Keepm]

Conrac monitors were used extensively by the DoD in Automated Test Stations - the Navy used them in the CAT-IIID and RadCom stations (both Grumman, used to support the bygone A-6 Intruder and F-14 Tomcat aircraft.

I fixed a total of two - one had no G-2 voltages (was an open 180K resistor) and the other had a nasty arcing in the focus lead as it left the HV cage. A little RTV Silicone sealant fixed that.

There were Grumman supplied, original Conrac manuals for the monitors - the Navy never produced any manuals themselves.

Very durable - they survived the vibration and G-cycling produced by the catapaults on an Aircraft carrier, but the ship's degaussing system used to give them hell - hence the manual degaussing switch on many models.

If a Google search comes up with nothing, I'd be hard pressed to tell you where to get a manual. Good luck - those monitors are solid, American made and sharp!

Cheers,
