Transformer Core Grades

We usually provide quotations to our customers with different transformer core grades. For expert users, they will know what those transformer core grades means and what the impacts are to the results or sound. For those that are rather new to DIY or to transformers, they might find it difficult to understand.

We were thinking of writing an article to educate the users on the benefits of different transformer cores and that is the reason for the birth of this article. It just so happens that we previously came across 2 excellently written articles by Eddie Vaughn that discuss the pros and cons of different transformer cores. This saves us a lot of effort to reinvent the wheel and direct our efforts to keep up with the production schedules.

Please download these 2 articles and enjoy the read! We're not sure how long will these articles be kept in the vault. So, please do so before it is gone.

SE vs Push Pull Amplifier Part 1

SE versus Push Pull Amplifier Part 2

Part 1 focuses more on tube amplifier design and differences between different topologies or design circuits. Part 2 touches the "deep, dark secrets of output transformers", where most people are interested to know! It talks about various core types (EI, Toroid, C cores), SE and Push Pull output transformers, different core materials and many other details on transformer design.

It is YOUR lost if you do not download and read it. After you read it, you will gain better understanding of what the fuss is all about on different transformer core grades, types and design. You will appreciate more what transformer cores or grades that are used in your power transformers, chokes / inductors, inter-stage transformers and output transformers. The transformer myth is debunked in a bird's eye view.
