The RV12P2000 is a 'universal' HF pentode, possibly close in design to the American Acorn valve 954. The base has side pins and a knob can be screwed into the end of the base to act as a handle. This base arrangement prevented the stress on the glass to metal seal of the pins that caused problems for the Acorn types.
The RV12P2000 was produced in quantities larger than any other valve for the Wehrmacht. It was used in many stages of a a piece of equipment. The design allowed for it to function in RF stages up to the low VHF and even to generate up to 580 mW of output. It was also found as an oscillator, IF amplifier, audio amplifier and we believe also, in some cases, as a rectifier.
