You've clearly never had the "pleasure" of dealing with an ARP Omni then. The
tantalum capacitors in those tend to have failed long ago, although that's only
the tip of the iceberg when it comes to the Omni - the power supply has a design
flaw that causes components to die, and the sliders fall to bits :-/
