ADCOM GFA-545 II Amplifier & GTP-506 Preamplifier/Tuner Set - Tested & Working

For sale is a ADCOM GFA-545 II Amplifier with a ADCOM GTP-506 Preamplifier/Tuner. These items have been tested and are in perfect working condition and sound great together. These items are in good condition, but the amplifier has some scratches on the top from being stacked.
About GFA-545 II Amplifier: This robust amplifier is capable of operating into very low impedance or difficult speaker loads due in part to its high current design.  It is based on a triple Darlington configuration and uses no protection or current limiting circuitry other than the fuses used in the DC power supply voltage rails.
About GTP-506 Pre/Tuner:

The fully remote controllable Adcom GTP-506 breaks new ground by including two entirely separate tuner circuits that allow two different users to listen to their favourite stations independently of each other.

The GTP-506 is the perfect control centre for one, two or three zone systems. In combination with it's companion power amplifier, the GFA-5006, the user has tremendous flexibility in operating the system from its remote control in each zone or with in-wall keypads from other manufacturers. The Adcom system not only has enormous control capability, but also has the exceptional sound quality characteristic of all Adcom products.
