There is at least one other madison member that I know of, but I am not sure if he purposely does not display his ID. I just joined, very cool site.
As far as the $400, they were listed at 400 yesterday. I am kind of interested in the focal components, primarily for the tweeters. Do you need that amp/deck? Maybe we can lowball the guy and get some cheap gear and sell the rest or something.
Believe it or not, a replacement set screw is impossible to find. It's an M7x1 thread about 20mm long, and not even Fastenal nor Grainger have it on their sites. Ace has a good selection but all they have are M6 and M8 sizes. Menards no...Farm & Fleet no. I lost it like 3.5 years ago when I took the amp out of my old car.
Still works...just ghetto as hell...don't really want to try and tap it to the next Standard size...
Yeah, if there is any hope for selling that amp you need to tap that thing out and put something less janky looking in there. If your too lazy, or don't know how I could do it for you. I am extremely well equipped for tools.
You could always drill the center of that bolt out, thread it, and cut it off and thread a set screw into the bolt effectively making a collar for a different sized setscrew if you were so inclined, and didn't want to drill the amp.
hows that for a run on sentence?
BTW; In all seriousness nobody is going to buy that amp like that. I remembered the ad and that was the only part I could recall.
How is the set screw going to be held into the bolt? I understand the threading of the bolt, but I mean the set screw would just unscrew instead of the bolt. JB Weld is nice for holding nuts and bolts in place but it's not good when stressed.
