put it in your amp only turn on the filament and let it run for 5 or 6
hours until you turn on plate voltage. I know a ham that had 34 304tl
tubes and that what he did.

Subject: [TenTec] OT: Need advice checking out a stored 3-500
(Posting this for a local fellow ham who currently isn't on the web)
As the subject line says, a local ham friend of mine asked me today about
how
to go about checking out/waking up a 3-500 (Z?) that came as a spare with
his
AL-80A when he bought it a few years back. He's not really sure how long
the
tube had been sitting around unused/un-exercised before he bought the amp.
I've seen conflicting info on how to go about it, and the last time I had
my
hands on something like that was 30+ years ago when I worked in the
broadcast
industry before I switched to a different career. Any suggestions? Other
than
his amp I don't have any way that I know of to check it.
Contact me off list if appropriate.
BTW Ten-Tec connection: he's driving it with an Orion.
TNX/73, Al
