RE: Tubes

The tube killers (other than arcing issues) are current and dissipation.

Arcing is due to voltage. Absent a compromised envelope or a structural misalignment, usually not a problem.

Voltage times current make for too much dissipation.

I'm trying to think how one would have too much current but not enough voltage to kill a power tube - help me out.
