An excellent looking and operating Mc Martin TG-2/EBS Two-Tone EBS Generator. This was used for EBS weekly tests. It was tested on a digital scope with tones and levels looking good. If someone wanted a good steady two-two generator for transmitter testing, this would be a good source. Also those building a studio for their AM setup it was a required item in the rack, adds that realism for the authentic look. The mounting is for a standard 19" rack mount. It produces either 853 Hz or 960, or both up to +8dbm at 600 ohms. A steady or timed output is featured. A full description of the circuit is described in the included original manual. See the photos. I have more photos on Google Drive. Link is
