Classic Nelson Pass design. Pure Class A amplifier rated at 200 watts per channel into 8 ohms and 400 watts into 4 ohms. A true vintage heavyweight with the build quality and performance Threshold is known for.
This amplifier drives my Magnepans effortlessly and delivers an outstanding clean sound stage. Almost enough power to arc weld with it.
Approximately eight years ago it was professionally recapped and serviced by a technician who specializes in Threshold equipment. Cardas speaker binding posts were installed during service. The amplifier is fully functional and in extremely clean cosmetic condition.
This is not a lightweight piece. It weighs 83 pounds and is built like the serious late 70s high end amplifier it is.
Specifications:
Power output: 200 watts per channel into 8 ohms, 400 watts per channel into 4 ohms, 700 watts mono
Frequency response: 20 Hz to 20 kHz
Total harmonic distortion: 0.05 percent
Damping factor: 300
Gain: 27 dB
Dimensions: 19 x 6.94 x 17.25 inches
Weight: 83 lbs
Year: 1979
Asking $2,500. Open to reasonable offers. This is a properly functioning, serviced, and very clean example.
Serious inquiries only. I have video of the amplifier operating and can provide contact information for the technician who serviced it. I am located way off the beaten path, up croy road and up a mile long dirt/gravel drive. You would need a SUV or Truck. A honda Civic wont make it without bottoming out on some parts of my drive. So If you are SERIOUS and would like to demo it and willing to make the drive up, I can schedule a listening demonstration. Otherwise, I can bring the AMP and meet you or bring to you depending on where you live. This is a heavy, heavy amplifier.
