Over 90 tube amp topologies examined, further evidence of how audio output transformers inescapably present limitations and compromises.
Menno Van der Veen presented at 118th AES a paper detailing a universal audio output transformer system that “includes all possible variations in topologies. The system contains 90 variations (at least) and some of them have never been constructed until now.” With technical discussion, the paper provides further evidence of how audio output transformers inescapably present limitations and compromises. Compare this with patented ZOTL Technology in GAGA, which does actually provide picture-perfect response without compromise.
