Econco rebuilds external anode tubes of a certain size.  They won't
deal with anything below around 2500 or 3000 watts plate dissipation.
Small tubes for ham like 8877s can't be rebuilt.   You may not be
missing much.  What I've heard is that the rebuild jobs used in
broadcast (nowadays tube FM rigs) don't last all that long, maybe a
year.   This is why the industry is going solid state.  The cost and
availability of tubes is forcing them.   Fortunately for ham, tubes
when cared for, last a long time and there are plenty of 3-500s etc.
out there.
