Hello all.  I'm in the process of restoring an SX-25.  The original audio output xfmr had been replaced by a previous owner.  The replacement is not correct and also has an open winding.  So, if you have one or know of one, I'd be interested.  The xfmr is designated T4  in the schematic.  It's connected push-pull with two 6F6 tubes.  Not sure, but the transformer may be the same used in the following receivers, S-11, 12, SX-16, 17, 28, 28A, 32, 42, 62. These receivers all had PP audio output sections using 6V6, 6L6 or 6F6.
Thanks, Frank
