Published ratings and characteristics promoted from the supplied Telefunken source where explicitly readable. Telefunken REN1004 indirectly heated 4 V, 1 A receiving triode. Original approximate data indicate 100–200 V anode operating range and a published transconductance of 0.02 mA/V, equivalent to 0.000020 S. The operating-voltage range is not identified as an absolute maximum rating.

Source-dependent data

Operating conditions by source

Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
