| ###  yes, and it for pulse operation.   It appears it might be 100ma, non 
pulsed.
But under typ operation it shows 30-40 ma.. and this is pulsed, and average 
during the 
pulse.  Max grid current is listed as  +/- 100 ma.
##  I also looked at the 3CX-5000A7... and it has a 50 watt grid rating.... 
but no max grid current.
The yc-156  is  listed as 25 watt max grid diss.   So I don't know what to 
believe.
