DO24 Mullard red white print pair balloon valves MO-V works PX25 PP5/400 equivalent

Description

An audio output valve for powerful receivers and amplifiers, this is the Mullard DO24 direct equivalent of the MO-V PX25.

The DO24 is a high magnification valve and will give a very large output for a grid input voltage of 24V R.M.S.

The amount of low frequency amplification in previous stages is thus kept at a minimum.
