O12 is used backwards as the input in early UA 1176 limiters. O-1 tranny used in original UA 610 tube preamps. Don't know if you have documentation for utc but CJ has some. He's the resident transformer Doctor (or madman). :green:

O8 was sold as a "plate to line" transformer. Primary 15K, secondary 50/250/600 Ohms.
