Adcom GF566 pre-amplifier. 

Great sounding and highly regarded American built stereo pre amp. 

This unit has one of the best phono preamps you are likely to find at this price point.

This is an US 110V model but comes supplied with a suitable transformer. 

In overall very good condition but there is a problem with the CD input.  The selector swirled may need a clean or a replacement but Ihave just always used the aux or one of the tape inputs for CD.

I had always planned to fit a 240v transformer but have never found the time. 

I can supply a pdf copy of the service manual.
