Description
Two pairs of rare Mullard AC044
On the left a apir of Mullard ribbed plate AC044 fully tested 46mA and 48mA
On the right a pair of Mullard chrome finned plate fully tested 47mA and 45mA 100% emission.
The AC044 is direct equivalent of the PX4 a super-power output valve for powerful receivers, capable of driving moving coil and large speakers at full volume.
Type AC044 is a directly heated power triode for the output stage of receivers and amplifiers where a considerable undistorted power output is required with an anode voltage up to 300. For this purpose the AC044 valve has exceptionally good characteritics and is particularly suitable for operating moving coil speakers at large volume without distortion.
The filament of the AC044 is of the robust oxide coated type and may be heated from A.C. through a suitable step-down transformer
Filament Voltage 4
Filament Current 1.0 amp
Anode Voltage 300
