    A Coppery Oddity

    Or maybe it's just another one of those "weird to me" items. A mono HK receiver (TA-1040) with a distinctive case. As always no affiliation. https://columbus.craigslist.org/ele/d/columbus-harman-kardon-ta1040-festival/6929633260.html Hk_ta1040 by CT_Ohio posted Jul 8, 2019 at 9:29 PM

    Recapping and restoring a Harman Kardon 330C

    A fellow AK'er asked how to fix static in one channel of a HK330C that persisted even after a good deoxit'ing. I recommended replacing all the electrolytic caps and known-noisy transistors. Here is a quick idea of the caps and transistors involved. This is a quick answer so far, so I may have...

    HK AVR 125 Buzz

    I have an HK AVR125 with a loud buzz at low volume. The more you increase the volume, the lower the buzz. I have tested for a ground loop by popping the ground off an old power strip. I have nothing plugged in but the L/R front speakers, no inputs, surround off. It happens in all inputs. I...

    Harman Kardon citation 16 has a strong hum on the right side. Any help?

    A few years ago my HK Citation started to hum quite loudly on the right side. I have the technical manual but I think it's the large 1,000 microfarad capacitors that have given way. Has anyone else had this problem?
