I have a pair of Maggies that I'm going to replace the tweeter wiring. This isn't hard I have done this before. The question though is the mid/woofer voicecoil. It has some areas in the middle, around the tuning dots, that is lifting. I would rather not replace the entire voicecoil but spot fix those areas with the Gunn style of using contact cement. I have used the Gunn style for delam at the top and bottom of the coil "turns" with good results before. Does anybody have experience with this or see any problems with my idea?
yes I have seen this before......most of the time it when a panel has feel over...trapet air....look at this pic..........the mylar had to move as far as you see the wire is from the mylar.....the great thing is the mylar well go back to norm .....even if it rips the mylar.....but it leaves the wire as you see.....in pic
I have got Magnepans off CL that were even more pulled away...from falling
an yes MR Gunns dap fix well work ......but this is the one place I use the 3M 77 spray.........I don't pull or bend the wire..... I just spray the spot an.wire well................ then don't do any thing it must dry for 20-30 min this is a must!......then just lay the wire over...I try to keep the wire from tuching the other wire if you can....but if thay do it ok..........the wire wiill not line up with the mag gap in that spot but it well not change the sound...........it works great.....

I've fixed lifted spots on my MGIIIs with thinned contact cement, about 2 parts thinner(MEK I think; I just tried various solvents til I found one that worked) to 1 part contact cement - the stuff that comes in a 16 oz can, usually used for formica. Painted it on with a toothpick, wire and membrane. After it reached the tack stage, I pressed the wire down with my finger wrapped in plastic food wrap to insure it didn't stick to my finger. After about 30 minutes, I put another layer of the thinned cement on locally for reinforcement. That was about 5 years ago, and they're still working fine.
