The VX3061 is an experimental UHF disc seal triode. The connections left to right are:- anode, grid, cathode/heater and heater as centre connection.We have the military version here.We have no operating details for this device.It is interesting that the successful UHF and SHF devices such as the DET22 are very similar to this early design that looks much like the DET29.The planar envelope is 14 mm in diameter and, excluding the base pins, is 60 mm tall.Reference: Observation. Type VX3061 was first introduced in 1958. See also 1958 adverts. |
