I have two Boonton 260-A Q-meters (and one manual) that i would like to move. They both have worked, but i only have one detector tube between them - and i think one of the front panel pots is bad. Since it is a power wire wound with a switch, i would not know how to find a replacement. Make offer for one or both on an as-is basis.
The magnetron is a GE GL-5J29 and has no magnet. It is about 6 inches long and 2 inches in diameter. Marked "confidential" and probably made for use in the UK for radars to detect enemy planes or rockets. It has a good vacuum and the filament is OK. The glass envelope lets one see everything, including the water-cooled "U" resonator and filament. It should be a good collectors item.
