The 'Magic Three' Valves
collections G8LSD Valve Collection |
The CV452 was designed as a demodulator and first audio stage in superhet receivers. All stages share the cathode which would be held at ground potential.
From the side the structure is revealed. The central dark cylinder is the triode section and the two wings are the diode anodes, one for AGC and the other for AM signal demodulation. The inverted U shaped wings are mounted on either side of the central cathode tube and are separated from one another by the micas.
The thin glass tube envelope is 17 mm in diameter and, excluding the B7G base pins, is 46 mm tall.
