Measurement of 30 output transformers for SE300B

Posted by Jmmlc (A) on December 11, 2009 at 07:03:49

Hello,

During the last European Triode Festival, aside the "transformers shootout" , I could perform measurements on 30 output transformers for Single End 300B amplifiers.

The document with the measurements is downloadable at the bottom of the page:
