GZ37 CV378 MULLARD BLACKBURN NEW OLD STOCK RECTIFIER MANUFACTURED SEPTEMBER 1962
On offer today we have a boxed new old stock Mullard tall form GZ37 also labeled CV378. In this format, each section posesses a tubular cathode which is strapped to one side of the heater to avoid the need for the additional heater power and consequent increased heat output which could be detrimental with such a narrow envelope. The tall form envelope is 42 mm in diameter, and excluding the IO base pins is 130 mm tall.
This device carries perfect full white print and the Mullard old shield markings as well as the military cartouche which cites Mullard Blackburn manufacture during September 1962.
