5670 / 2C51 / 396A
The 5670 (main equivalents 2C51 and 396A ) is a purely American-designed Double Triode even if it was also produced in Europe and up to the Soviet Union. Its use was basically in VHF in Military apparatuses. Being a high gain tube, NOVAL base and with easy to use Low Frequency application data, it has had and still has an interesting application in PRE-amplification and similar circuits.
