Left channel issues, amp or crossover? in Technical/Modifications Posted January 13 2 minutes ago, RandyH000 said: 1)- do not try adding a 3rd amplifier ---since 2 amps have been damaged so far - 2)------in either case , these crossovers need to be tested - by a qualified technician -and you might as well rebuild them to factory specs - @JEM Performance is the current Klipsch Authorized repair center for these crossovers -----https://jemperformanceaudio.com/ 3)- test with an Ohmmeter the DCR of the woofer-midrange -tweeter of both speakers ---post the results on this thread - Thanks Randy. The Nad amp is at my fathers, it has actually been working fine. He went through and heated up all solder joints on the Adcom preamp but never tested it before to see if it was working. He has them both working now. I had assumed I just lost the left channel on the Adcom when the Nad amp direct wired worked fine. Does JEM repair or sell kits with original parts or same specs? I'm not looking for any "upgrades" like crites.
