Re: 6550 closest to GE. Current production only

First off, 70mA is not zero mA. I run 35 Watts at idle, not zero.

Where I got my data sheet does not list the absolute maximum just the design maximum, so I kind of lumped design max with absolute max.
That was the source of my problem. Now I understand.

Do you have a better data sheet link? I got mine from triode electronics http://www.triodeel.com/tubedata.htm

All my data sheet knowledge has been in semiconductors. So my predisposition is that maximum is maximum. They always have one section very clear with absolute maximums.

So the fact that the design max and absolute max are different make sense but it just confused me since I did not have all three ratings in front of me.
