Notes

Grids 1 and 2 form the internal oscillator; grids 3 and 5 are signal grids; grid 4 is a screen grid. Grid 3 is tied internally to grid 5.
Maximum ratings: plate voltage 300V, screen (g4) voltage 100V, plate dissipation 1.0W.
Conversion transconductance (Gc) at Va=250V, Vg4=100V is approximately 450 umhos.
The 5750/6BE6-W is the ruggedised military version with tighter tolerances.
European equivalent is EK90 (Mullard). CV453 is the British military designation.
