Giving away an Adcom GFP-555 II.  It works and has been well cared for.  However, it has a hiss when the tone control button is pushed "on" (to enable the use of bass & treble controls}.  And a couple of times the hiss has appeared without the tone control engaged.  It goes away after turning it off then on again.

It's backup to my backup preamp now so it's redundant, but I don't want to trash it.  Original price in 1995 I think was $500.  Anyone want it?
