The 6AG5 is a low power amplifier beam tetrode that features a low anode to cathode capacitance and has two small anode plates at a wide separation from the cathode.

It is clearly designed for voltage amplification but we have no details on an actual specified use.

The thin glass tube envelope is 17 mm in diameter and excluding the B7G base pins the valve is 47 mm long.
