Adcom GFP-750 Preamplifier, Professionally Upgraded:  Box/Remote

For offer is a beautiful Adcom GFP-750 audiophile preamplifier designed by nelson pass and introducing the topology which made Pass labs and their product so desirable. This is a single owner component from a non-smoking pet free studio. This unit has been professionally upgraded with contemporary matched Nichicon FW and KW Muse capacitors, Dale Precision capacitors Siemens Relays and freshening of all components which have drifted out of original design specifications. All components have been matched to within .5% tolerances. All switches and mechanical parts cleaned and relays and passive components matched for perfect performance exceeding the original engineering specification. 

The cosmetic condition is exceptional a perfect faceplate, about .5mm of the lens nib on the aux lamp missing ( no effect on functionality),  untarnished brass switch plate, clean placarding and markings no wear to stencils and lettering and perhaps only one light scuff to light to show in the photographs on the top (perhaps from a cardboard scuff) please do not base your consideration on the description but rather the photographs of the actual componet in this listing  

Please forgive the acurate but duplicate photographs as the Audiogon server froze while posting and replicated the images {but there are lots of high rez shots of this great component!]

 This is simply an exceptional component in excellent condition  enhanced to realize the full AUDIO potential of the Nelson’s Pass design with the original box. .  Please: shipping  only to the western US (or local pick up).  double boxed and insured. 

Thank you for your consideration
