    Been watching lots of videos for tips. I'll be using a 1/8" Mohair Roller to apply the adhesive and pros say not to use a J-Roller. Use a spatula because you can apply 8 times more force.

    Being on AK makes for a great crowd and look for more stuff to save from a landfill. Hope to see the results.

    Additionally, I'm curious over the crossover work. Why update the caps at all? Original crossovers were only electrolytic to the super tweeter. I sort of feel you downgraded the caps.

    I LOVE that you kept it walnut, true to the original. I am truly in awe of your dedication to this project. I have a mint pair of the 200W model so if you need any measurements or pics etc let me know.

    I assure you this mod improved the HPM's. It's well documented on this site.

    The hardware showed up and it's a perfect match. Not as easy as you think to find these. 20180714_112102.jpg 20180714_112117.jpg

    Really a nice job you are doing there. One of the more enjoyable I have read lately. I have been studying up on the crossover mods and can't decide follow some of the recommended mods or just replace the existing components as is. Any advice or links to infor on what you finally decided to do with yours? Thanks again for the awesome job! Enjoy!

    I was just posting with questions about restoring a pair of these and someone pointed me to your thread. Glad to see it’s a recent and on going project. Keep us updated and I’ll be following this thread. How did you end up going about the veneer removal? I think you said solvents didn’t work so what did you do? Also, I’m not very knowledable on veneer installation but 1/16” sounds thick. Will you see edges when finished because of this or will your finishing compounds blend these edges in? I know the installation order is important but still wondering. I have some 3m backed veneer in storage but not sure if it’ll be a good choice or not.

    Thanks for your time and information!

    My plan is to do a test piece and go through the entire veneer process. Then use my stains and test results. Acetone was good for the front "face" veneer strips but I used a belt sander, then orbital, then hand sanded for perfectly square edges on sides. Used my level and used wood bondo to make it true. I work for the airlines and summer flying is insane this summer. Everyone has money lately. The key is the glue. If its lumpy you will have lumpy veneer. No spray glue. Using gel glue and rolling it on. An expert advised this.
