CV378, MILITARY SPEC GZ33, MULLARD, WHITE PRINT, I576 K3,, BLACKBURN, MARCH 1954 PRODUCTION
A very nice EX EQUIPMENT device this, carrying good Mullard Old shield markings in white ink on one side and the military markings on the other. What makes this example scarce is it carries the GZ33 notation - normally paired with the CV3745 notation rather than the cv378. Did Mullard have a glut of GZ33 and decide to relabel the higher rated valve for miliary CV378 use? .. Device tests as full emission for each section within the envelope.
