Default 814 as Triode / Max. Ug2 voltage

Hi folks,
Has anybody tried out the 814 pentode as triode ?
There are very nice curves on Pete Millet's site: http://www.tubebooks.org/file_downlo...4%20curves.gif

Thing is, anode voltage (and thus G2 voltage) goes well beyound 1kV. Furthermore the drawed Operating Point is at about 700V.
But: In the Datasheet they give a max. of 400V Ug2.
The reason might be that the datasheet only gives RF operating data. Max Ug2 for AF operating is usually much higher. But I'm still in doubt. Anyone has some facts ?
