jr Jacob Roschy	CL4*Tetrode Außer als normale Pentode wurde die CL4 auch als Beam Power Tetrode gefertigt, zuerst von Telefunken mit Strahlbündel- Blechblende wie die 6V6, später mit nur auf zwei Stäbe abgemagertem "Bremsgitter". In dieser Version wurde sie auch besonders von RFT- Betrieben der DDR geliefert. 05.Feb.2007 Jacob Roschy
