Mechanical dimensions
All linear dimensions are in millimetres and describe the valve base and its pins. They are not socket-hole diameters.
The pin circle passes through the pin centres. Pin spacing is the straight-line distance between adjacent centres. ≈ denotes a value calculated from nominal geometry; ± denotes a tolerance, parentheses show limits and ≤ denotes a maximum.

In depth
G10G has ten asymmetrically distributed peripheral contacts. In the bottom view, contact 1 is separated from the rest by a wider gap. The overall layout distinguishes this base from other ten-contact constructions.
The G10G designation must accompany the illustrated geometry. Decal B10B, ten-contact Stahl and CRT sockets are not equivalent merely because the counts match. The layout drawing also does not determine the electrical functions of the ten positions.
In the Telefunken EL152/FL152 example, pins are 2.5 mm in diameter and 8.5 mm long, on a 25 mm circle. These dimensions belong to that version. They remain separate from envelope dimensions and are not a universal specification for all ten-contact bases.
EL152 and FL152 are radiation-cooled transmitting pentodes, also intended for low-frequency amplification. Their different heater voltages do not change the lower layout shown. Ten contacts still do not permit a pinout to be transferred to other families.
