[Hammarlund] SP600-JX-17 HOOK UP TO DRO-50

Sat, 6 Dec 2003 20:45:38 -0600

Hey Guys,

        Do you know of any of these that have actually worked properly.  A
buddy of mine had one and never could get it to work...added the preamp but
still no joy!  I would love to have one for each of my 600's once the bugs
are worked out..

Cecil...
