Unusual & Specialized Electronics Repair

We Love Challenges!

Not all electronics fit into standard categories. EFIXLAB specializes in repairing unusual, exotic and custom electronics where standard repair shops say "we don't do that". If it has circuits and needs fixing - we're interested!

What We Consider "Unusual"

Vintage and Obsolete Technology

• Retro computers - Commodore, Amiga, Atari, early PCs
• Vintage audio equipment - tube amplifiers, reel-to-reel recorders
• Arcade machines - game boards, CRT monitors, power supplies
• Old industrial controls - relay logic, vacuum tube circuits
• Film projectors - 8mm/16mm/35mm electronics

Scientific and Research Equipment

• Laboratory instruments - oscilloscopes, spectrum analyzers, custom test equipment
• Data acquisition systems - custom DAQ boards, sensor interfaces
• RF test equipment - network analyzers, signal generators
• Particle detectors - photomultipliers, scintillation counters
• Spectrometers - mass spec, optical spectroscopy electronics

Custom and Prototype Devices

• One-off designs - prototype boards, custom automation
• Academic projects - university research equipment
• Special purpose controllers - unique industrial applications
• Modified equipment - customized commercial devices

Entertainment and Show Technology

• Stage lighting - DMX controllers, moving head fixtures, dimmers
• DJ equipment - mixers, CDJs, effects processors
• Pyrotechnic controllers - firing systems (safety-critical)
• Animatronics - servo controllers, pneumatic control

Exotic Industrial Applications

• Semiconductor equipment - wafer handling, plasma systems
• Vacuum systems - turbopump controllers, gauges
• Laser systems - control electronics, power supplies
• Textile machinery - Jacquard controllers, embroidery systems
• Food processing - specialized control systems

Typical Challenges

No Documentation Available

• Reverse engineering circuit topology
• Tracing signals and power rails
• Identifying custom/unmarked ICs
• Solution: PCB tracing, logic analysis, educated guessing

Obsolete Components

• ICs no longer manufactured
• Proprietary parts with no replacements
• Solution: NOS (new old stock) sourcing, functional equivalents, FPGA replacement

Unique Technologies

• Tube circuits - high voltages, specialized knowledge
• Nixie tube drivers - 170V DC logic
• CRT deflection circuits - high voltage, high frequency
• Solution: Specialized knowledge base, period-correct components
