That one sounds like a monster.  It should handle the 4-1000 project 
well.  I don't know what happened to this one.  It was far more than 
the power capability or the rig but something got one of the contact 
fingers.

Thank you for thinking of me Bob.  Another guy thinks he may have 
one but it will be tomorrow before he can look.  Another possibility 
is one out of something Ameritron makes.  Say the two 572B amp or 
so.  It will be Monday before I can look.  They are selling those 
parts individually now and the prices are really cheap.
