Die meisten Röhrendatenbücher führen die seltene Type UAF21 nicht. Siehe auch hier. In der "Radio Technik" 1949 Heft 9 wird diese Röhre von Ing. L. Ratheiser (nach Tungsram-Unterlagen) beschrieben.
Vergleichstype: UAF42, jedoch in Rimlocktechnik mit anderer Sockelung und kleinerer Heizleistung, bzw. kleinerer Steilheit und höheren Kopplungskapazitäten.
