BigShot - ABY Passive

I'd like to make a simple passive "Y" splitter to feed two amps even if the amplifiers have large "ground" voltage differences. The "BigShot ABY" appears to do that but I can't find the model of the transformer used in the circuit and I don't need the A-B selection ability.

is the block diagram for the BigShot. Can anyone suggest an appropriate make/model transformer?
PS - also attached
is the spec sheet for the OEM transformer.

Those things are like $50. You're not going to save nearly enough money to even justify the time spent sourcing that transformer.

The Lehle LTHZ is perfect, but expensive.
It's used in the P-Split, maybe you should buy that used. It's the sturdiest pedal that I've ever had.

Got a response from EDCOR. They recommend:
WSM6400
1/2W stereo unbalanced line level signal to a mono unbalanced or balanced line level signal
$10.23 each.
