Comment:

The Regulator M100 is is a vintage scanner, and as it is a pre-SMD scanner, it's not a big deal to add a discriminator output.

The discriminator IC is an unknown 18 pin DIL IC. It is stamped 'Regency 600-565'.

Using an oscilloscope, pin 10 of this IC appears to contain the unfiltered baseband signal. A solder point next to pin 10 appears to be connected directly to the IC. A 10k resistor is soldered to TP5. The resistor can be mounted vertically.

Because the discriminator output contains a slight IF component at 455 kHz, the other lead of the resistor is connected to a grounded 2.2 n capacitor. This creates a simple RC lowpass filter with a cutoff frequency of about 7 kHz. The IF signal is suppressed effectively. The ground lead of the capacitor can be connected to the shield of the IF coil nearby.
