Exchange is about $600/pair.
Ribbon Repair Kit is $140 plus shipping.

$232 for an exchange pair including shipping and another $30 for return shipping of the damaged ribbons (2 years ago). Of course it helps to live on the west side of the pond.
Lucky you!

You americans could help us europeans! We send our ribbons to and you send them to Magnepan for exchange. Then back from you to Europe.
In Europe it is awfully expensive having them repaired.
Ordered a ribbon repairvkit from Magnepan this summer. Unfortunately they cannot send you the original 3 ohm ribbons for older Tympani IV/IVa, prior to serial number 020949 (mine have 020838). The 2 ohm ribbon plus 1 ohm resistor ribbon is said to be not as good sonicly but more robust.
The recent 3 ohm ribbon is narrower. Maybe it can be used in the old ribbon cages too? Sure the gap between the magnets is wider, thicker dots of adeshive is a must. The magnets are also thicker in the recent ribbons, a loss of effiency would be the case. Maybe it will hold up to the original Tympani IV/IVa ribbons?
Tweeter..my bane as far as it comes to Maggies too..that and living abroad.
Yes it's a shame Magnepan no longer manufacture the old wide 3 ohm ribbon. It's thinner than the other 2 types and must have been more prone to breaking. I can't think of any other reason why they changed to the thicker wide 2 ohm wide ribbon and 1 ohm resistor (because the 2 ohm definitely sounds inferior to the original wide 3 ohm and gives less output due to the resistor). This change happened in both the Tympani IVa and MGIIIa throughout their manufacture.The newer narrow 3 ohm ribbon is the best sounding one. I compared all three types of ribbon a few years ago. At the time I too toyed with the idea of fitting a newer type narrow 3 ohm foil into an older wide cage, but myself and Satie came to the conclusion that there would be two main problems, the first being a wider magnet gap giving less output, and the secondly it would be hard and maybe not possible to put in the damping dots needed.
If the magnets are also thicker on the newer cage that means fitting a narrow foil in a wide cage would give even less efficiency. How much is hard to tell though I guess the only way to find out would be to try it. If it's too inefficient it might not be useable.
Magnepan won't ship whole new narrow tweeters abroad. My only other hope to fit new narrow tweeters into my MGIIIas was to try to find a pair of post 3.3R Maggies with non working drivers (even blown tweeters would be ok as you could get the ribbon repair kit, you just need the new cages). Been looking for 4 years now though and still nothing has turned up on that front!
