<Never heard of the FU728F.  My concern would be that it vanishes like
<the 4CX1600.  Interesting about the failures.  I guess the type number
<is telling.  Say "FU" out loud.

It's a chinese version of a 4CX-1500B..on steroids.  It's a popular tube
that was used in Emtron amplifiers...and is currently being used in
OM-Power amplifiers.
