peak4 Posted June 11, 2016 Share Posted June 11, 2016 (edited) That sounds interesting; does the rod attach end on, or does it need to end up looking like a flag on a pole? Can you see what colour the original soldering was? That always assumes it was soldered of course; could it have been spot welded in the same way that internal wiring in a valve was? See this rather good film of a French ham making a valve himself. I find it captivating. I assume it's outside the glass envelope??

Nagel Posted June 11, 2016 Share Posted June 11, 2016 I've seen that French movie before since I'm interested in physics/vacuum tubes. Good isn't it. The rod and plate are detachable from the tube, they screw onto one of the terminals - the small plate has a hole on it for the screw. It's the same type as the tubes on this site - https://www.orau.org/ptp/collection/xraytubes/x-raytubes.htm Link to comment Share on other sites More sharing options...
