Need GU-81m data

[woody]

I am trying to find data on the GU-81m pentode I am realy interested in how much the grid can disipate if I use the tube
in inverting mode and what the cathode voltage/current requirements are.

Thanks in advance,

You seem determined to get Inverted Mode to work.

Have you seen Steve Bench's work:

It might be good to try e-mailing him too.

Please let us know if you make any progress!
