Sansui OPT's

Hi TJ,

I imagine that the AU-111 sound/fame comes as a result of its OPT's which were made by Hashimoto. They are still being made, and are for sale. Check out FD's link.

Can't help you with the winding info, except that the primaries on mine measure 4K, and the CFB is about 10% Check out a thread at AA:
