Extras ▼

 

The KT67 is a high slope HF beam tetrode with a mutual conductance of 13.0 mA/V. The data-sheet gives the use range as series stabiliser, video amplifier and cathode follower.
The GEC paper label. The control grid has heat sink vanes on the top of the supports. The beam plates are topped with screening plates. The cathode is a wide rectangle.
The end of the anode. To the side, the middle of the working face, are additional heat radiating fins.
Another view of the anode. The additional heat sinking is formed is a narrow U section.
The wide glass tube envelope is 40 mm in diameter, and excluding the B9G base pins is 77 mm tall.
