CassetteMaster | Gray Audograph Dictating Machine @CassetteMaster | Uploaded 5 years ago | Updated 10 hours ago
This long video shows a very interesting machine--the Gray Audograph.

It shows voice and music quality with both built-in and external speaker, as well as restoration work with me and SpeakerFreak95.

I got this unit from jrcstudios on YouTube.

A video of this on SpeakerFreak95's channel is here:
