I-V Plate Curve Characteristics

3/28/1999 9:37 AM
Tim	I-V Plate Curve Characteristics I'm designing a tube amp and I have a set of plate curves for 6L6-GC's that have the screen grid constant at 300 V. Unfortunately, I need to set the screen grid to 350 to keep my control grid from going positive. But I don't have a set of curves for that set up. Is there a logical way (without a tube curve tracer) to modify the curves for one set of characteristics to a different set of characteristics (This seems kindof stupid, especially since most tube data books only provide one REALLY TINY plot to design from).
