The 7189A is an improved version of type 6BQ5 / EL 84. It has identical characteristics regarding the typical application circuit of the EL 84, but is designed to withstand higher plate voltages and higher plate dissipation. The same applies to the screen grid. The screen grid is additionally connected with pin 6, the control grid additionally with pin 1 (for better heat dissipation).

Die 7189A ist eine verbesserte Version der EL 84 / 6BQ5. Sie hat identische Eigenschaften bezüglich der typischen Anwendungsschaltung einer EL 84, besitzt jedoch eine größere Anoden-Verlustleistung und ist für höhere Anodenspannungen geeignet. Gleiches gilt für das Schirmgitter. Das Schimgitter ist zusätzlich mit Stift 6 verbunden, das Steuergitter zusätzlich mit Stift 1 (für bessere Wärmeabfuhr).
