Rare vintage Heath Schlumberger SG-72A tube Audio Generator.

It is basically a single note drone oscillator. It produces a pleasant wave somewhere between a sine and triangle to my ears. Comes with a 1/4" female adapter cable.

-Multiplier/Coarse + Fine Hertz knobs select frequency
-Output Attenuator and Level control knobs

Everything is functional and working well except for the big meter on the front. The meter doesn't seem to move at all. The oscillator itself is fully adjustable and sounding good. Most of the knobs have been replaced and are not original. The unit has not been opened so I believe everything inside is original.
