MC1496 is one of the oldest chips, which after 50 years (1972) since its first production by Motorola, is still in production. Regarding supplied power from a double source, things are a bit simpler, because the chip was initially designed for a single power source.
In all schemes where there is a dual power source, the negative (-) source can be connected to ground, and very small bias adjustments will be needed.
I tested the MC1496 in the SMD version at +3.3V and it works decent as a balanced modulator.
See that major Spice simulators have MC1496 model, and you can play with it.
