I have checked the Estel website and they do not have any information for toroidal transformers, you might try with CSE http://www.cse-transformers.com It is also in Thailand and provide useful information about toroidal transformers
We are currently in an audio projects and we are searching for good quality toroidal transformers from Thailand. Can anyone introduce us any manufacturer in Thailand? We know that Thailand is an emerging market for toroidal transformers with competitive prices and good quality.
For China...
