Transformer test data posted here - UTC, Marinair, Beyer, Sowter, more

Since I'm sitting on a decent pile of transformers I decided to put them through a standard set of tests and record the results for future reference. I tested UTC, St Ives, Marinair, Freed, Beyer Dynamic, ADC, Peerless, Sowter and Webster Electric transformers so far, and I have another 15 or so models by UTC, Haufe, Marinair, Triad, and others that will be added to the list.

The data is entered into an Excel spreadsheet and saved as a PDF. Some of the data is entered "raw" and other numbers are calculated to arrrive at input : output impedance, frequency response and maximum operating level.

Here is a link to the list so far:
