CV1120 / CV1290 halfwave rectifier
See below for more examples of this valve.
Internal views. The mica shield presumably protects the electrode structure from the getter.
The CV Register shows the CV1290 as equivalent to the SU2150A, and the CV1120 as a possible replacement. However the example in the first picture above shows both SU2150A and CV1120. See also CV1001
