Is anyone familiar with this tube.  It is a dual pentode/triode and I 
have two of them.  Both exhibit a bit of strange behavior in my tube 
checker, a Western Electric KS-15650-L.

When I set the checker for the pentode section the directions say to set 
the bias for 1 volt.  Then when I press the test button the bias jumps 
to 2.4 volts.  The triode section checks correct.

Does anyone have experience with this tube and can tell me if this is 
something particular to it?  In all my born days, I have never seen 
anything like this.  I would consider it a short, but the short test 
does not indicate thus.
