The VT25 transmitting triode has a large square four pin base as can be seen from the picture. The anode box is quite large and blackened to radiate heat more effectively.Operating frequency would be in the HF range and the output power was of the order of 36 Watts.
The anode assembly can be seen in this picture. For the construction of the electrodes See DET25.The wide glass tube envelope is 51 mm in diameter and, excluding the L4 base pins, is 150 mm tall.Reference: Data-sheet & 1005. |
