Analogue Solutions Synthesizer Repair
Professional Analogue Solutions Repair & Diagnostics in the USA
Precision Voltage Labs provides professional repair, diagnostics, and calibration services for Analogue Solutions synthesizers, Eurorack modules, desktop instruments, and sequencers. We support customers throughout the United States with reliable mail-in repair service for both current-production and legacy Analogue Solutions products.
Analogue Solutions has been producing distinctive analog synthesizers and modular systems since the mid-1990s and is widely respected for its commitment to true analog design. From Eurorack modules and desktop synthesizers to full-size keyboard instruments and modular systems, Analogue Solutions products are known for their rich sound, hands-on interfaces, and robust engineering. Instruments such as the Colossus, Vostok, Fusebox, Leipzig, and Nyborg have earned a dedicated following among musicians seeking authentic analog character and performance-focused design.
As these instruments continue to see years of studio and live use, reliable repair and technical support remain essential for maintaining long-term performance and reliability.
Our repair process focuses on careful diagnostics, component-level troubleshooting, calibration verification, and long-term reliability. We have extensive experience servicing analog synthesizers, control voltage systems, sequencers, power supplies, MIDI systems, keyboard electronics, and mixed-signal architectures commonly found throughout the Analogue Solutions product line.

Diagnostics & Technical Repair Process
Modern Analogue Solutions instruments often combine:
precision analog circuitry
control voltage processing systems
switching and linear power systems
MIDI and synchronization systems
keyboard scanning electronics
sequencer architectures
through-hole and surface-mount assemblies
analog audio signal paths
Symptoms do not always reveal the underlying failure. An instrument with tuning instability, sequencing issues, MIDI problems, or intermittent operation may involve multiple subsystems including voltage regulation, calibration drift, control electronics, timing systems, user-interface circuitry, 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
Through-hole repair and rework
Surface-mount soldering and rework
Oscilloscope-based signal tracing
Voltage rail analysis
Audio path troubleshooting
Oscillator tracking calibration
Filter calibration and testing
MIDI diagnostics
Sequencer troubleshooting
Connector and mechanical repair
Power supply diagnostics
All repairs are performed in an ESD-safe workspace using professional electronics diagnostic equipment.

Support for Current and Legacy Analogue Solutions Instruments
Analogue Solutions synthesizers are widely respected for their authentic analog sound and long-term reliability. Many instruments remain in active use for decades, making maintenance, calibration, and repair increasingly important as components naturally age.
Whether you own a large-format Colossus system, a Fusebox synthesizer, a Telemark desktop instrument, or a vintage Eurorack module, professional diagnostics can help restore proper operation and extend the useful life of your equipment.
Precision Voltage Labs provides diagnostic and repair support for both current-production and many discontinued Analogue Solutions products 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 Analogue Solutions instruments are large-format, limited-production, or difficult to replace, we can provide additional packaging recommendations to help ensure safe shipment during transit.
Synthesizers and modules should always be packaged carefully using anti-static protection and adequate padding during shipment.
