Ed Anderson,
When we spoke a couple of weeks ago = at KLKR,=20 you mentioned a great brazing rod for aluminum.  Was it New=20 Technology's HTS-2000.  If so may I ask where you bought, = direct from=20 the vendor or were you able to find a smaller quantity than 1 = lb..  If=20 this is not the vendor or product may I ask again what it = was.
 
Thanks,
Joe
