Flag ship model from the early 1990s when Harman Kardon was still serious about hi-fi. 170W per channel with high current capability provide huge bass drive capability. Remote control with MM/MC capability and separable operation as pre-amp or power amp makes this a very flexible amplifier. Please see attached specs page.
Please do not hesitate to ask questions!
I have the original sales brochure, manual, unused remote and a copy of the service manual.
