    Anyone know the blue book of the Adcom GTP-600 preamp?
    I might buy a preamp from a military guy who has the original box, manual and remote. What is the bluebook of the preamp in middle condition?

    Also a little history of this amp would be nice.. Thank you

    I see they went on eBay for $102 and $103, lately. There was also one that went for $50, but it appears to be an anomaly due to a seller with no feedback and a unit without its remote.

    The Audiogon Bluebook average price of the GTP-600 is $320.00. The last one sold for $240.00 and the lowest selling price was $150.00.
