Adcom GFP-565 pre-amp

That's still is an excellent full function pre-amp. Its highly regarded. Many vinyl lovers its a way to get into vinyl on the cheap and still retain high end sound for pennies. I believe this is a John Curl design? In its day and now it can be a wonderful addition to a vinyl spinning audiophile looking for a well made pre with tone controls and flexibility.

They seem to be selling for between $200 and $350 on Ebay, depending on condition. Just check the completed listings tab on Ebay.

Still a demand for them on Ebay. I had no trouble selling mine. And speaking of vinyl lovers, it has a very good phono stage.

Audiogon lists it's bluebook value at $320.00 but that is an estimate. Best of luck.
