What is 6k4p tube?
  • The 6K4P (6К4П Cyrillic) is a high frequency pentode from the Soviet era. Vibration resistance is given in the data-sheet and this suggests a special quality valve. The opening in the anode reveals the three wire grids. The mica supports are quite thick and this will help in vibration resistance.
  • The anode face view with the grid supports visible above the top mica.
  • The thin glass tube envelope is 17 mm in diameter, and excluding the B7G base pins is 51 mm tall.
  • Reference: Data-sheet. Type 6K4P was first introduced in 1954.
