Orthogonal Devices Module Repair
Professional Orthogonal Devices Repair & Diagnostics in the USA
Precision Voltage Labs provides professional repair, diagnostics, and calibration services for Orthogonal Devices Eurorack modules. We support customers throughout the United States with reliable mail-in repair service for both current-production and legacy Orthogonal Devices products.
Orthogonal Devices modules are known for their sophisticated digital architectures, deep feature sets, and exceptional engineering. Despite a relatively small product lineup, Orthogonal Devices has produced some of the most influential and widely respected modules in Eurorack history. Modules such as ER-301 Sound Computer and ER-101/ER-102 Sequencer systems have become central components in advanced modular systems due to their flexibility, performance capabilities, and long-term reliability.
As these modules continue to see years of studio and performance use, reliable repair and technical support remain essential for maintaining long-term functionality and preserving these highly sought-after instruments.
Our repair process focuses on careful diagnostics, component-level troubleshooting, calibration verification, and long-term reliability. We work with both analog and digital Eurorack systems and have experience servicing digital signal processing systems, embedded computing platforms, display systems, storage media, precision analog circuitry, and mixed-signal electronics commonly found throughout the Orthogonal Devices product line.

Orthogonal Devices Modules We Commonly Service
We service many Orthogonal Devices products including:
ER-301 Sound Computer
ER-101 Quad Sequencer
ER-102 Expander

Legacy Orthogonal Devices Products
We also service discontinued and legacy Orthogonal Devices modules that remain active in studios and performance systems throughout the modular synthesizer community.
Diagnostics & Technical Repair Process
Modern Orthogonal Devices modules often combine:
digital signal processing
embedded computing systems
microcontrollers
precision analog circuitry
switching and linear power systems
display and user-interface electronics
storage and memory systems
advanced sequencing architectures
real-time audio processing systems
Symptoms do not always reveal the underlying failure. A module with no output, unstable operation, boot issues, or user interface problems may involve multiple subsystems including voltage regulation, firmware, memory systems, storage media, digital audio processing, display hardware, or analog signal path faults.
At Precision Voltage Labs, repairs begin with detailed diagnostics to identify root-cause failures before unnecessary parts replacement occurs.
Repair and testing capabilities include:
PCB-level diagnostics
Surface-mount soldering and rework
Oscilloscope-based signal tracing
Voltage rail analysis
Audio path troubleshooting
Storage and memory diagnostics
Display diagnostics
Encoder and control diagnostics
Digital signal processing diagnostics
Firmware-related troubleshooting where applicable
Connector and mechanical repair
All repairs are performed in an ESD-safe workspace using professional electronics diagnostic equipment.

Support for Current and Legacy Orthogonal Devices Modules
Orthogonal Devices products have become highly valued due to their unique capabilities and limited availability. Many users rely on ER-301 and ER-101 systems as central components within their modular workflows, making reliable repair support increasingly important as modules age and components experience normal wear.
Because Orthogonal Devices modules are no longer produced in significant quantities, professional repair services can help extend the useful life of these increasingly difficult-to-replace instruments.
Precision Voltage Labs provides diagnostic and repair support for both current-production and legacy Orthogonal Devices modules whenever repair is technically feasible.
Mail-In Repair Service
Precision Voltage Labs provides secure mail-in repair service throughout the United States.
Customers can contact us for:
repair evaluation
shipping instructions
packaging guidance
turnaround estimates
diagnostic consultation
Because many Orthogonal Devices modules have become highly sought after and difficult to replace, we can provide additional packaging recommendations to help ensure safe shipment during transit.
Modules should always be packaged carefully using anti-static protection and adequate padding during shipment.
