Working on scaling my meters today using that Meter program from Tonne Software.  For those that don't know i'm using the GM3SEK Triode Board and it has outputs for Grid and Anode metering onboard, so i'm working on getting those meters ready today.

I can only find that the GI7B has a max Plate/Anode current of .600mA, so figure a 1a scale will be plenty on the Plate Current meter.

What about the Grid Current meter?  I can't find any info showing what the max current is for the Grid on these tubes.  I want to make the scales nice and neat with colored bands showing the normal operating range, a quick glance to see if i got a problem, etc..

Someone on here must know!  None of the english or russian spec sheets that i can find mention grid current.

Thanks and 73,
