Harmon Kardon HK6100

Hey, you are right null object, it works for me now. This will make my rebuild and insane modding allot easier as I can at least keep some of the original circuitry.

My HK6100 died not too long ago after using it on a preamp that blew an output transistor in a noisy fasion, only one channel works now and not sure why because the outputs did not blow out, but the wimpy driver transistors would get really hot, so maybe they died.

Don't really care either way because I only payed 20 bucks for it just to be experimented with any ways.

must have been a glitch, the link worked for me this time.....

very strange.... i just noticed the tone controls are part of the power amp feedback network..... it can be done, but most often tone controls are part of the preamp. this actually directly changes the frequency response of the amp itself....

So, after some brut-force searching I found the shiny. I hope it will help.

Mine HK started resonating and then dropping out one chanell after about half a hour of 30% operation. I measured 10mV DC on output durring load, therfore i assumed, that dropping out was not speaker protection. Maybe it is just overheating and new thermal compound will help.
