Specialist Electronics
Service
Vintage audio · analog synthesizers · custom PCB · EOL industrial · reverse engineering
We repair what others won't take on. Tube amplifiers, analog synthesizers (Moog, Roland, Korg), non-standard PCBs, electronics from defunct companies without documentation. 24h quote, 12-month warranty.
Specialist electronics — full range of services
Tube amplifiers and vintage audio
Marshall, Fender, Vox, Mesa Boogie, Hi-Fi (Leak, Marantz, Scott). Tube replacement, electrolytic capacitor replacement (recap), transformer and voltage regulator service. THD and power measurements after service.
Analog synthesizers (VCO/VCF/VCA)
Moog Minimoog/Subsequent/Sub37, Roland SH-101/Juno-60/Jupiter-8, Korg MS-20/Poly-6/Monopoly, Oberheim OB-8. VCO, VCF, VCA, CV/Gate module repair. Post-repair calibration. Electrolytic capacitor replacement.
Non-standard PCB — reverse engineering
We repair printed circuit boards without documentation. Schematic reconstruction from physical PCB by reverse engineering, damage identification, component repair or reproduction. 1-off and small series support.
EOL electronics — manufacturer no longer exists
Machine controllers from defunct companies (Hartmann, Contraves, Cincinnati Milacron, Hardinge). White-label OEM electronics without manufacturer. Diagnostics, replacement sourcing, functionality restoration.
Turntables, reel-to-reel tape recorders
Technics SL-1200/1210, Thorens TD, Revox B77/A77, Studer A807/A810. Head amplifier, motor and power supply electronics service. We don't replace mechanics — we focus on electronics.
R&D prototypes and custom electronics
Repair of R&D device prototypes, non-standard electronic test circuits. Damaged module replacement, embedded software debug (Arduino/STM32), oscilloscope and logic analyzer measurements.
Why EFIXLAB?
- We take on difficult cases — no documentation, no schematic, unknown manufacturer. We diagnose electronics using analog and digital methods.
- PCB reverse engineering — we reconstruct schematics from physical PCBs, identify components, and repair. Unique experience with hard-to-source devices.
- Wide range of vintage equipment — we work with both 60s-70s electronics (tubes, germanium transistors) and the latest SMD electronics.
- Repair after quote approval — diagnostics cost is included in the repair price. If repair is impossible, we inform you and charge only the diagnostics fee (300 PLN net).
- Precision soldering — we work under a stereoscopic microscope, T12 precision soldering iron, SMD/BGA station.

Describe the device as precisely as possible — even "unknown manufacturer, machine from 1986, no documentation". The more details, the faster and more accurately we can respond.
Questions about specialist electronics service
Yes — that is our specialty. We perform reverse engineering of the physical PCB, identify components using standard measurement methods, diagnose the fault and repair. In some cases repair is impossible — we inform honestly after diagnostics and charge only the diagnostics fee (300 PLN net).
Yes — we repair analog synthesizers, including CEM3340/AS3340, SSM2044, Curtis chip replacement, VCO/VCF/VCA calibration, electrolytic capacitor recapping. All popular models from the 70s-90s.
Tube replacement + capacitor recap in a tube amplifier is typically 300–700 PLN (labor), plus materials cost (tubes, capacitors). Damage repair 200–500 PLN. Quote after diagnostics (300 PLN net, included in repair price).
Time depends on fault complexity and component availability. Simple repairs 2–5 days, complex reverse engineering 1–3 weeks. We inform about estimated time in the quote.
