Before I go snapping up cheap TV dampers for use as rectifiers, got one question: What does it mean on the specs when the following is written...
Ehk +100V -900V
The 900V is encouraging, but the 100V is of concern. I want to be sure these tubes can handle high enough voltages in typical tube amp service. Thanks for any help.

Let's look it up...(searching for tube manual)... hmmm... maybe this big red book... Ehk : "voltage of heater with respect to cathode" - so the heater can be 100V positive or 900V negative with respect to cathode - or the cathode can be 900V POSITIVE with respect to heater.
But if you have a separate heater winding for rectifiers, use it.

On the topic of damper diodes, anyone have experience with these?

I picked up a few in Antique Electronic Supply's last sale. In the current sale still under $3 a pop.
