For sale, we have an Adcom GTP-550 Preamp with a built in Tuner. The unit is in very good physical condition and in good working order. We cleaned all the pots and switches on the unit and then treated them with Deoxit F5 and D5 respectively. All inputs were checked for operation and they all performed as they should.
Physically there are some blemishes on the unit, but overall the condition is very good. There are no dents or deep scratches. The preamp was well cared for, and it comes with the original box. See pictures for further details.
