NOTES
* I do not yet know any correct designation for this tube base type; "SK‑116" is the part number of a compatible socket.

Some (most?) tubes with this base type are actually made with 12 pins and the gap created by cutting one pin. Since I know of no instance in which this 12th pin is not cut, and all sockets appear to be 11-pin, I consider this to be an 11-pin base.

Siemens data for tube types ZM1120 and ZM1122 states that the tube socket should be rotated 11° counterclockwise (relative to my drawing above) for upright presentation of digits; however, my examination of several ZM1120 tubes does not support this assertion.

Arrow Arrow points away from tube outline indicating top of symbols for end-viewed tubes, points toward tube outline indicating direction of viewing for side-viewed tubes.

Pins are shown as looking at the base of the tube; i.e. "bottom view".
