Default Tube grid resistance for 6P45S, fine?

From the russian datasheet, it says:

Сопротивление в цепи 1-й сетки, МОм:
при фиксированном смещении 0.5
в схеме строчной развертки со стабилизацией 2.2

Which translates to 0,5 M.Ohm resistance for fixed bias.

I put 268k value for now, because I'm tempted using low values coupling caps, which are too big/infoundable in big values.

But can I trust this datasheet and go ahead with 268k?
The specs are for beam tetrode mode. Does it differ for triode strapped, because it is in triode mode now?

The amp sounds and works good 10 hours for now with this setup, no runaways.
