Under DigiKey look up "MET-09" (as an example) or "Tamura" and "Audio" ...... there are many listed.
I was going to put it between the detector and the OpAmp to cut down on unwanted signals. Those little things can be easily shielded too with some copper tape.

Were you thinking of putting the transformer between the detector and
the op-amps? Where they are likely to do the most good is between the
radio and the PC.
