[Amps] Amperex 3-1000H

[W5CUL]

Thank you to all who have replied, both on and off list.  Looks like I will
not be using a 3-1000H as a standby.  Thank you again.

The H is a low mu tube and not suitable for class be grounded grid.
If you put it into an amplifier in place of a 3-1000Z it will draw loads of 
current
and get red hot.
