- Notes
-
Class "B" Speaker-Amplifier Unit.
The extra power obtainable from Class "B" output valves compared with that obtainable for the same current consumption from ordinary triodes or pentodes often produces a marked improvement in the performance of a small moving coil loudspeaker from the point of view of quality as well as volume.
Many makers are ensuring that their loudspeakers shall be properly appreciated by incorporating a Class "B" output stage in the loudspeaker unit. The unit is connected to the anode circuit of the last valve in the set, which then becomes the driver.
