KT61, MARCONI, BLACK BASE, JULY 1946 PRODUCTION
On offer today we have a beautiful Marconi device. It tests as 100% emission as you can see from the attached test data label courtesy of our AVO VCM163. The envelope carries the etched ellipse cartouche and a tricolour Marconi decal. The black micanol base is tight to the envelope and shows clean uncorroded pins - a simply super device.
