CV1630 / 5C/450A pentode
This is described as an RF suppressor modulated pentode
*: At a max frequency of 10MHz
**: At: Va=2.5kV, Vg2=600V, Vg3=0, Vg1=-90V (AC filament) or -85V (DC filament)
The pins are arranged as follows: when viewed from the base, the pin on its own is the screen grid; the three pins in an arc are filament, control grid, filament. At the top of the valve, the anode connection is above the single base pin, and the suppressor grid the other side.
The envelope incorporates a glass support for the electrode structure.
