1016 dual noise / random voltage generator

This one has been modded, note the extra switch on the panel, and contains a tuning circuit. There is a 1964 tuning fork oscillator inside. There are pics of a similar item with its guts exposed on this page, scroll to the bottom.

 foam is crumbling away

 you can see the tuning fork in these pics, presumably the coils on either side of it pick up the vibrations.

 cans are TI 741s

 copper is well corroded

 Safely packed away.....bye!
