Famous Marantz Model 140 Power Amplifier with its Model 3200 Pre-amplifier, in perfect working and cosmetic conditions. A very good design without compromise from the Marantz U.S. engineering team. Perfectly manufactured in the Japan factory in 1976. The amp is power rated at 2x75W at 0.2% THD in 8-ohm loads, but in practice the measurements show 2x110W at 0.1% THD, quite a good margin of power! Fully serviced and measured at the ACDC Lab: - New capacitors (recap) when required. - New light bulbs (long life LED-based). - Full cleaning of potentiometers and rotary switches. - All alignements have been performed (DC balance, Bias, Vu-Meters) - All signal paths fully checked and measured. The measured audio performances are better than the manufacturer specifications, especially: max power output, harmonic distorsion at high power (quite excellent) , bandwith flatness (very goog), signal noise ratio (excellent) . please see the pictures with lab measurements screen snapshots. With owner manuals, service manuals and cables as shown in the pictures. The devices can be seen/listen in the area of Namur and Liege (Belgium). Free shipping is possible in theses areas.
