Details:

Note pictures and ask questions before buying. All analog hand built. Sold for parts or repair. The components have age and definitely need servicing before it will function.

This came from a local university storage offer. It was designed as a teaching tool. I do not have the amplifier housing or a manual or any other components apart from pictured to go with it.
