4	NF-Leistungsverstärker Audio Power Amplifier Characteristics

4.5	Tetrode oder Pentode im Eintaktbetrieb Single-Ended Tetrode or Pentode

Alle Eintakt-NF-Verstärker werden in Klasse A betrieben. Wenn nichts anderes angegeben, ist das Bremsgitter g3 mit der Katode verbunden.
All single-ended audio amplifiers are operated under Class-A conditions. The suppressor grid g3 is tied to the cathode, unless otherwise specified.
