Hello there,
Happy New Year!
I am a final year Audio Engineering (Tonmeister) student from the University of Surrey (UK). For my final year project I'd like to investigate how chaning a deisgn variable within an audio transformer can affect its sound and performance. I am probably going to focus on microphone input or line output transformers. After doing research, I think it would be possible to investigate one of the following variables:
-Core material
-Core shape
-Core size
-Winding technique and size
If there are other interesting design features that you think has a large impact on sound and you think there is an interesting experiment that could be done to investigate this, please let me know!
In order to do an experiment I need to find a range of transformers that only vary in one of the above parameters. But this is proving hard to find. I am most interested in core material and shape. Many of the manufacturers with a wide range of transformers, often have lots of different winding ratios, which would affect the various parastic inductive and capacative values, making it difficult to draw a direct comparison between them. So if anyone knows of any range of transformers that I could investigate, that would be very helpful!
I am also interested in winding my own transformers, in order that I can carefully control all the variables exactly to my own design. However, I am finding it very difficult to locate different transformer cores. If anybody could help me with this too it would be much appreciated!
Lastly, if you could recommend any interesting academic literature that you think might help with my paper, that would be much appreciated! I have already read Bill Whitlock’s chapter from the Audio Engineering Handbook, some AES and IEEE papers, some articles by Crowhurst and the Transformer and Inductor Handbook.
There are a lot of clever and experienced people on this forum. Any help given to me will be very gratefully received!
