Heathkit tube amplifier project AC-11 mono best to stereo converter.

Product Name: Heathkit tube amplifier project AC-11 mono best to stereo converter.
This Heathkit model ac11 looks like it is an incomplete project. It is supposed to have three tubes that are missing. All of them are 12AU7. There is an enormous number of RCA terminated cables coming out the back. There was also a power cord. That's all I know about this unit. It will obviously require some work before it is awesome. It looks like it was made in the late 1950s or early 1960s. Tubelover tells me it's a stereo receiver best that could upgrade mono radios of the day, and could add-on to various brands!.
