Thanks for the input guys, tonight I'll swap the crossovers and see if the noise follows the left crossover to the right speaker. I'll also retie the screws in the process. a couple of pics from the inside.

@kink56The woofer wires are going to the k22. Pretty sure about that. @ricktate good point. The source is the same as the sellers house. I brought an iphone and ran it straight to the amp. This way I knew the music, and controlled the volume with spotify. Not ideal but it works. but I did also test at home with a yamaha receiver and apple tv as source. Got the same issue.

Thanks for the suggestion CEC. did double check the screws, but didn’t actually unscrew them first. Will try.

Hi everyone! First post from a longtime lurker I have been following this forum for quite some time, especially the Super Heresy treads. Until this sunday I have been listening to a pair of RP-160, but a good deal on a Heresy popped up near me and I had to take the chance on them. Living in Denmark Klipsch are a rare and expensive bread. The speakers sounded nice when demoing them at sellers house, but I didn’t get the chance to look inside the cabs before getting them home. Actually they did sound super fun. Much more snap and “live” feel than the rp-160. Inside it looks all original, k77 tweets, k55 mid push terminal, k22 woofer and the relatively rare Type D crossover. Unfortunately, after getting home the left channel started making distortion noises and and clicking sounds. The right one did to actually, but much lower, and this is where I need advice on troubleshooting the issue. I ran some sound sweeps and am pretty sure the offending sound comes out of the K55. this is what I have done so far: 1. Made sure the issue is not on the amp. When swapping the channels the issue stays on the left speaker. The amp is a little quad 306 cracking little guy that amp by the way. 2. Made sure the k55 are working. Both measure 9.6 on my multimeter. (More or less) 3. Swapped out the k55 with a pair of GPA 909. This I did to figure out if the diaphragms in the K55 was off, but the skratching distortion was also present with the GPA. And the issues was still more prominent on the left channel. 4.Double checked and tied connections I am suspecting the issue lies in the crossover then. The caps are original brown Type D ones after all. This makes them 40 plus years old? I have some 2mF Solen caps on the way. What is left: Ground loop? Autoformers? Wires? Anything else? Down the road I might go the Super Heresy path, but first I want to iron out the problems and enjoy the originals. What now o wise ones...?
