Jim,
Did you ever get to speak to anyone at Eimac about where the
getters
were at in a 3-500Z? That's a question I'd say a few of us would
like
to find out about as I think there is some erroneous info floating
around on the net about it. One said it was the anode itself, but
it
doesn't get hot enough in my opinion to do it, and would actually
have
relaeased hydrogen gas if, a certain gettering material were
applied
to it. Any thoughts on this?

### No I have not. 1 e-mail to eimac ought end the
discussion . Rauch claims amperex etc... all use zirconium
coated anodes... and gettwring is done when tubes shoe
colour... aprx 800 deg C. I'm inclined to agree. A 3-500Z
has no internal getter........ so it's either the tube has
zirconium on the anode..... or it has NO getter at all !
