Tung-Sol was a privately held company and was run like a laboratory. This gave Tung Sol vacuum tubes a reputation of having some of the best metallurgy and chemistry that has ever been pulled off in actual production.[1] The Tung Sol brand name is now owned by the New Sensor Corporation, which is the same parent company as Sovtek and the old Electro-Harmonix.[2]
