All in same format. Under these conditions the grids would require 108 volts peak to peak to achieve full output.
The Millard do24 has very similar ratings to the PX25 but the anode looks much like the px4.
This example is branded as a Marconi product as can be seen below, note also the hand construction with the band held against the pinch. Only one available. With transformers of the period being less efficient than later designs an audio Power amplifier using a pair of these valves was a substantial piece of equipment, and heavy. Filament VF 4 volts if 2 ampere direct parallel, ac dc the PX25 is one of the all time classic audio output triode.
Identical to CV1040 PX25 NR47 vr40 vt104 GPO 10e rd27as similar tubes normally replaceable slightly different do24 pp5 400 base Europe 4 pin a, 4a, b4, since was used by radio TV reception etc. Last four images are from other opened cartons of CV1040 that acquired at the same time with this pair. New old stock nos valves, under rare CV1040 type designation, in its original packaging. A single ended design running at 400 volts at 63 ma 25 watts input would produce about five to six watts of pure class.
