Transformer data and schematics!
This data is available on DVD-ROM from www.theoscilloscopestore.com
I'm starting to accumulate transformer data and associated schematics. Thanks to Tony Daggs for many of the scans!
Many files on this site, especially scanned documentation, are in Adobe Acrobat (PDF) format. I recommend that if you don't already have it you download the latest version of Adobe reader. Some files have compressed images that may not work correctly with older versions of Acrobat reader.

Thordarson:
I scored a couple of Thordarson 22S39 output transformers on e-bay, mixed up in a batch of flyback transformers. I thought that the datasheet (which was in the box) and the accompanying application schematic might be of interest (at least historically), so here it is...
