Yes, the spark suppressors go bad. All it is: a capacitor across the switch contacts. A replacement capacitor would be easy to source, but it wouldn't LOOK like the original Garrard part.
A typical electronics hobbyist probably has something suitable in his "junk box." Just make sure it is of high enough voltage. On 120v in the USA, a 400 volt capacitor would be safe, allowing for spikes, most surges, and the peak-to-peak AC voltage.
