Anyone read Russian?

Jeb-D. · 27th February 2008, 05:19 AM

Could you please help me understand this datasheet. Are the max limits listed? Those curves are given for a Vg2 of 150V, correct?

I've read that this tube is the same as E180F 6688, but the curves provided for those tubes don't quite match up.

Thanks!

Thanks a lot!
Those curves are for Vg2 of 150V right? I can see a 150 in the text below, but am not positive if that is what it is for.

0V on third grid, 150V on second grid.

--- for anode dependence,
- - - for second grid dependence.
