Description
AudioMagical introduce a rare pair of Mullard DO26 balloon shaped .
The DO26 is used as output valve in powerful receivers gramophone amplifiers and small public address equipments.
The DO26 has a lower amplification factor than type DO24 and therefore requires a greater grid excitation voltage of the order of 65 volts R.M.S.
This valve has a very low anode impedance and is therefore capable of giving a substantially greater output than DO24.
