    Re: A 416 dilemma. What to do?

    Well anyway what was this thread about ?? Sheez, Hi Pano,Please bring back some nice photos of the fest or the OB you are working on.Would love to see them.

    I think it has more to do with this particular pair of drivers than anything else.Were talking about 1 pair of drivers out of thousands and thousands of drivers.To me this seems very rare to come across this situation were the Alnico V fails to recharge.

    Unless there are others that have had this same problem.

    I think the cause has more to do with material than GPA I have dealt with them (Bill and Steve) on several occasions each and have never had a problem.Oh yeah I had one problem there was 2 lock washers missing from 1 of the Large Format Driver Studs & Gaskets (Hardware Package) I had ordered.And Bill offered to send an entire new package for 2 missing Lock washers,told him not necessary.

    We are talking about a pair of LTV drivers aren't we.

    But Pano your original question was what to do. 90 some posts later question still stands.I wish I had an answer to help you my friend.But at this point I would NOT put anymore money into these drivers,there has to be an issue with the Aluminum-Nickel-Cobalt material.It is quite intriguing because they had to be OK when they were new,so what happened to these magnets. This question probably will never be answered unless you know where and how these drivers were used their entire life.

    Just a little something on magnets and magnetising:

    I would be tempted to try re-charging one speaker(the weaker one) as the paper indicates that the magnets should take re-charge.

    Cheers, Marshall.
