Yamaha PA-D015 Adapter for YV-2700 Vibraphone – VFM42800

The Yamaha VFM42800 AC ADAPTOR PA-D015 B ASSY is the current genuine Yamaha power supply for the YV-2700 vibraphone series. It replaces the discontinued Yamaha part WU274000 (listed as “AC ADAPTOR PA-D015// B YV”). This adapter provides regulated DC power to the YV-2700’s motor drive/control system so the resonators can spin and produce vibrato at adjustable speeds. 

On the YV-2700 and YV-2700G, the vibraphone’s motor (YVM-200 drive unit) runs from an external Yamaha adapter rather than internal mains. The PA-D015 is the adapter Yamaha specifies for UK / EU use. 

This is an original Yamaha spare part. Yamaha spare parts can have extended lead times when out of stock. Please contact Ev-Entz Music for an estimated availability date.

Key Features

• Correct Power Supply for YV-2700 Vibraphone
  This is the PSU Yamaha lists for the YV-2700 and YV-2700G vibraphones. It powers the vibraphone’s motor controller so you can run the rotating resonators and adjust vibrato speed (typically 25–145 rpm depending on model/drive unit). 

• Yamaha OEM Replacement (Updated Part Number)
  VFM42800 (AC ADAPTOR PA-D015 B ASSY) is the updated Yamaha part number. It supersedes earlier Yamaha SKUs such as WU274000 / “AC ADAPTOR PA-D015// B YV.” Using the new number ensures you’re ordering the currently supported assembly from Yamaha.

• Designed for European / UK spec units
  Yamaha documentation lists the PA-D015 adapter as providing DC 15V at 1A for European models, while North American units use a different adapter (PA-130 at DC 12V, 1A). That difference matters — using the wrong voltage can damage the vibraphone’s motor driver. 

• Stable, low-noise power
  A proper Yamaha supply keeps the motor speed smooth and the controller quiet. Worn or incorrect generic adapters can cause the resonator fan speed to surge, click, or stall. A correct PSU keeps the modulation even, which is important for recording and concert work. 

• Future support / serviceability
  Because this is an official Yamaha replacement assembly, percussion techs and ensemble managers can document it against the new code (VFM42800) for inventory and spares tracking going forward. 

• Lead time note
  Yamaha spare parts can have extended lead times when out of stock. Please contact Ev-Entz Music for an ETA before ordering.

Why Choose This Part

Vibraphones like the Yamaha YV-2700 rely on a powered drive unit (YVM-200 on YV-2700 / YV-2700G) to spin the resonator fans and create tremolo/vibrato. If the adapter is missing, damaged, noisy, or the wrong voltage, you lose speed control or the motor won’t run at all. 

This Yamaha-specified adapter delivers the correct DC output for the instrument, keeps the motor controller happy, and avoids the hum and instability that third-party generic power bricks can introduce. It’s also the cleanest way to get a discontinued vibraphone back to full performance, especially in schools, theatres, and hire fleets where these instruments still see daily use. 

Because Yamaha has updated the part number over time (from WU274000 to VFM42800), ordering by the new code helps ensure you receive the correct current assembly.

• Current Yamaha Part Code: VFM42800

• Previous / Discontinued Part Code(s): WU274000 (“AC ADAPTOR PA-D015// B YV”) and related PA-D015 references such as WU167800, listed for the YV-2700 vibraphone. 

• Instrument Compatibility: Yamaha YV-2700 and YV-2700G 3-octave vibraphones (and other YV-2700 variants using the YVM-200 drive unit). 

• Primary Function: External PSU for the vibraphone’s motor/drive controller (controls resonator fan rotation and tremolo speed). 

• Output (EU / UK spec): DC 15V, 1A (PA-D015) as specified by Yamaha for European YV-2700 models.

• North America Equivalent (for reference only): PA-130 adapter, DC 12V, ~1A, used on US/CA versions of the same vibraphone family. 

• Power Consumption (instrument side): YV-2700 / YV-2700G typically draws around 3.6 W when run from the PA-D015 adapter.

• Instrument Details (for context): YV-2700 is a 3-octave vibraphone (F3–F6 range) with aluminum alloy bars, adjustable height frame, and a motorised resonator system that runs 25–145 rpm via its controller. 

• Manufacturer: Yamaha / Yamaha Percussion (Yamaha Music Europe GmbH)
