Hello All,
I just thought I'd let you know the results of my little experiment. First of all I'd like to thank David for responding to my inquiry. Anyhow, I removed all the purient screw and exposed the mainboard and then I hit a major issue.....I couldn't figure out how to expose the inside of the mainboard because the circuit ribbons seemed to make such an exposure impossible....and looking at the soddering on the ribbons I felt reattaching those would be beyond my ability. So my answer was this. While it was open I noticed that when the jack was pressed down very slightly all problems went away. So I wedged a tiny piece of paper into the joint there with a little superglue...and voila! My headphones now sound amazing So when technical knowledge fails fall back on ingenuity. This is a subject that I do find very interesting though. David...would you, or anyone else, be interested in starting a portion of the webpage for those who want to learn something about taking apart and reassembling these badboys? I wasn't able to find anything about it online....but I think, given how fragiile these things are and how expensive they are to fix, that most people are in my boat.....i.e. you may as well try to fix it because it isn't worth it to send it off to be repaired. I DID notice while I was in there how far the quality has been reduced since the days of my R-70...which was pretty solid inside and out. Anyhow, thanks for all of your help.
