Magnepan MG1 rebuilds?


I have managed to aquire a pair of MG1's that are cosmetically in pretty good shape, but the former owner says they are dead. Before I dig into them myself to diagnose the problem(s), does anyone know if Magnepan will consider rebuilding these, is it worth it to send them to them, or, any third-party folks woking on MG1's?

I own a fantastic pair of MGIIIA's with modified XO and a sweet little pair of MMG's. I picked these speakers up for next to nothing in cost, drove to the guy's house and picked them up yesterday, so I have yet to look into the problem with them (if any).

Back in the late 80's I had a pair identical to these on extended loan from someone, and hated like hell to get rid of them because I loved the way they sounded in the room I had at the time.

I spoke to the folks at Magnepan, and in fact, they no longer repair or rebuild the MGI. I have decided to attempt the task myself. I purchased the tweeter repair kit for the MGI and a new pair of socks for the panels.

I have gleaned some repair/rebuild guidelines from Audio Asylum and will go from there.

Today - I took apart one the panels and found a break in the coil for the tweeter, and a fair amount of corrosion and discoloration on the mid/bass voice coil. None of the coil appears broken or corroded through so that may be a good thing. The state of the OEM banana connectors is pathetic and I will replace them with 5-way binding posts.

The job does not appear too complex, it just requires a deft hand with the adhesives, acetone, and solder (sp?).

Futher updates as they become available.
