Compatible Power Supply

This AC adapter is built for the Electro-Harmonix 44 Magnum 44W guitar power amplifier. It replaces the original US24DC-3000 supply so the pedal-style amp can run from a wall outlet. The package includes a Euro plug adapter for use on continental sockets.

24 V 2 A Output Headroom

The adapter delivers 24 volts at 2 amps from a 100-240 V AC input, matching the amplifier's rated 44 W draw. It will power the Magnum cleanly at typical stage volumes, but offers no extra current margin for daisy-chaining additional pedals.

Lightweight Wall-Wart Build

A compact brick enclosure keeps the unit light on a pedalboard or floor. The fixed output cable ends in a barrel connector that fits the Magnum's power jack, while the bundled Euro adapter slides onto the mains prongs for European venues.

Questions about this item

Will this adapter power my Electro-Harmonix 44 Magnum 44W amplifier if I keep using my existing US24DC-3000 power cord?

Yes, the adapter outputs 24V DC at 2A and is designed for the Electro-Harmonix 44 Magnum 44W Guitar Power Amplifier US24DC-3000, so it will work with that power cord.

How can I confirm the adapter is delivering the correct 24V output after I plug it in?

The adapter accepts 100V-240V AC input and provides a regulated 24V DC, 2A output; a multimeter on the DC plug should read approximately 24 volts when the unit is powered.

Does the package include the Euro plug adapter and the US24DC-3000 power cord, or must I buy either separately?

The box contains the HQRP AC adapter and a HQRP Euro plug adapter; the US24DC-3000 power cord is not included and must be sourced separately.
