[QUOTE="Ampdog, post: 767391, member: 144"] But that is what I confirmed, Charles! My problem is with the other set of data (Va = 400V) as also mentioned in my above post (this a.o. also per Osram data as I said and you suggest - but do consult the graphs, not just tabulated data!). But perhaps we better take this off- thread if still interested; I have a feeling not many members here care for arithmetical gymnastics. Error: I omitted to mention there that I was referring to the 400V data, thus the relevant sentence should have been: [i]"BUT: the second set of readings show Va (= Vg2; triode) [color=red]= 400V, [/color] Rk = 600 ohm and I(a + g2) = 62,5 mA. Those differ from the graphs."[/i] Kubusi's original topic was the usefulness of databooks, on which I think we agree. As said elsewhere, apart from my old manuals I have a thick folder of such data copied from internet so as to obviate endless search through so-called data sources, who mainly want to sell you something instead of providing useful design information.
