Watch and hear it play: https://youtube.com/shorts/YL8_G7eeOVA?si=M4q_y6bf_4K1sevk Power output: 100 watts per channel into 8? (stereo) Frequency response: 0.1Hz to 170kHz Total harmonic distortion: 0.06% Damping factor: 125 Input sensitivity: 1V Signal to noise ratio: 98dB Dimensions: 443 x 135 x 386mm Weight: 12.3kg The HK870, with its high instantaneous current capability of 60 amps, will develop far more power under peak loads than its rated 100 watts per channel. In fact, the dynamic behaviour approaches the ideal, in that the transient power nearly doubles into 4 Ohms and nearly quadruples into 2 Ohms. That means the HK870 gives you louder, clearer, cleaner sound than any other 100 watt power amplifier. The HK870 maintains a negative feedback level of 18dB, far below that of most power amplifiers. But there's much more to the HK870. We use a massive toroidal power transformer to eliminate the stray magnetic fields that cause hum. 4 dual polarity power supplies eliminate channel to channel interference, while assuring that the high level stages won't drain current at the expense of the low level stages. From a NON smoking home. This amp is excellent working condition. The power switch is bypassed, as shown in pictures.

HK 870 in working condition but due to modifications for parts or repair. I received the amp in this condition so Im unsure what was done to it. It is working as seen in this video, but there are no guarantees it will work upon arrival. https://youtu.be/AvOfUkw0Olc?feature=shared The 2 capacitors shown in the picture are not very secure, so I will put packing material around them before shipping. Youll have to take the cover off (1 screw missing) to remove the extra packing material.
