AC-3001 is a very rare preamplifier from AUDIO CRAFT. As it is a manufacturer famous for its tone arms, the PHONO is well made, and I think that there are few preamplifiers that can reproduce this level. It produces a very clear, solid and mellow sound. Even if you connect it to a modern system, it will produce an expressive sound image, and I think you will be able to use it for a long time. It is in relatively good condition and works without any problems. It can be used as a preamplifier, but it is also useful because it can be used as a PHONO equalizer on its own. (It can be connected without going through the volume or switch)
