No. The Hum Debugger power supply is VERY SPECIAL. It is actually part of the circuit. The power supply has the sensors in it that tell the Hum Debugger the specific sounds that it needs to subtract from the signal.

When you buy a used Hum Debugger, like from eBay, you need to make sure it comes with the original power supply. You can buy a replacement power supply, but they’re not cheap.

You can try a search for it, or you can send a note to info@ehx.com and they might be able to tell you where you can order one.
