[Boatanchors] Multicore solder specifications?

[Sandy]

The SAVBIT was very excellent stuff.  It didn't eat up soldering iron tips 
nearly as fast as the regular activated flux.  Somehow it got discontinued I 
suppose.

Someone said they suspect this is the "low residue" flux type, which had 
it's "troubles".  Another reply says he thinks it got discontinued.  (I can 
see why!)

Thanks for all the replies guys.  Problem discovered.

73,

Sandy W5TVW
