Hi I recently acquired an RCA BA-2B preamp, the input transformer is the right one labeled 901046, as in the schematic, but the output transformer is not the 901740 from the schematic, it is labeled M-146729 and has UTC F-1234 printed on the outside, and the pin layout is definitely not the same as the 901740 transformer. Anyone know what this transformer is, if it's actually the wrong transformer, and where I might find the right one? Thanks!
