### 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.
