After looking a bit closer..  Is the IF input at 20mhz?  I assume that I need
to add a swept local osc. in synch with the display sweep, and mixer, etc...
Am I on the right track?

Does anyone know the # of this??  (maybe 851A?)

Thanks again... sorry for so much wrong info on the first post... It must of
