these transformers in this '71 Superlead have no numbers or stickers on it. The guy who owns it since 30 years confirms that he himself never replaced them - although the written 'ALT' mark on the OT may suggest that they had been replaced one time. On the other hand I took a look at the Amp Archives and there seem to be some of those unnumbered trannies in some early seventies Superleads too. Is there any way to identify them?
