Notes

Contains three independent triode sections with separate cathodes. Designed for use with solid-state demodulators in color TV.
Interelectrode capacitances vary slightly between sections — Section 1: Cgp=3.2pF, Cin=4.2pF, Cout=0.3pF; Section 2: Cgp=3.0pF, Cin=4.2pF, Cout=0.4pF; Section 3: Cgp=3.0pF, Cin=4.2pF, Cout=0.54pF.
Transconductance spread between sections within the same tube can be significant — verify matching for critical audio applications.
