WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
For a push pull amplifier, the datasheet calls for a certain amount of plate current for two tubes. When the data sheet says "values for two tubes," does that mean that both tubes are drawing the datasheet value individually or is the datasheet value the combined plate currents?
I found that same at many datasheets. I reached conclussion that the values is for two tubes but just for some: usually pick to pick grid tension and power; the rest is just for single tube. This could be expossed better in the datasheet.
Usually, they're pretty clear about when they mean one or two tubes; there will be separate sections for single tube conditions and push pull. In the case of voltage ("tension"), it doesn't matter. Can you give an example of a datasheet where you think it's ambiguous?
Well, if I read "plate current" and "values for two tubes", I can understand it is the sum of the two plate currents, but it´s just one plate current. I think they could be more clear about.
