Application Notes
For large radiogram receivers or amplifiers, two of these valves in push-pull give an output adequate for almost all purposes. A large energised speaker should be used. If automatic bias is used, care must be taken that the resistance across the filament terminals is truly centre tapped to avoid hum.
