I have purchased a pair of secondhand OPTs from Audion, as used on the Silver Knight MKII.
According to the notes about strapping the primary windings, the transformers can be used for both SE amps and Push Pull. I knew that an SE OPT has to have an air gap to restrict the flow of DC to prevent saturation, so assumed that an SE OPT would only be used for SE applications.
Is it so that an SE OPT works well for PP? If so, these OPTs should give me a lot of flexibility in their use. They have 4 primary windings, and a UL tap is one possible combination.
