Thanks to both of you !
Guido is the guy who built a pair of 4435's in 2004, isn't he? Unfortunately he appears to be inactive for more than three years now .
Am I right that a remag job has to be done prior to a recone? And are ferrite magnets susceptible to lose their magnetic force the same way as AlNiCo's, even without opening the magntic circuit?
Best regards!
