Component-level electronics engineering, electro-mechanical reel calibration, and domestic mains conversions for discerning collectors across the UK.
Many vintage commercial cabinets operate on obsolete 115V or industrial high-draw wiring harnesses. We fit heavy-duty toroidal step-down isolation transformers, wire robust copper earth bonding directly to the steel chassis, replace vintage power cords with modern fused 3-pin UK plugs, and conduct full Portable Appliance Testing (PAT) certification.
Aging capacitors on original logic motherboards leak electrolyte and degrade circuit timing, leading to random resets and corrupt audio. We perform ultrasonic board washing, neutralize acid damage from vintage memory batteries, solder high-grade socketed coin-cell holders, and replace every electrolytic capacitor with 105°C Japanese components.
Mechanical reels rely on high-precision infrared photo-interrupters to synchronize physical positions with motherboard memory. Our bench technicians clean optical lenses, replace worn stepper motor bearings, balance reel baskets, and verify zero-backlash indexing through over 1,000 automated test spins.
Heavy commercial cabinets require specialized logistics. We do not use third-party general hauliers. Our two-man technical delivery crew transports the machine in cushioned air-ride transport, moves it safely past your domestic doorways into your chosen room, adjusts cabinet levelling legs, and guides you through operational maintenance.
Every machine certified by Retro Fruity Boards must pass this rigorous bench inspection protocol before delivery:
| Audit Phase | Engineering Procedures | Testing Equipment |
|---|---|---|
| Phase 1: Power & Mains | Switching rail ripple test (<15mV RMS), transformer insulation resistance test at 500V DC, continuous chassis earth ground bond (<0.1Ω). | Rigol Digital Storage Oscilloscope, Megger PAT Tester |
| Phase 2: Logic & Memory | Zero-acid motherboard inspection, CMOS memory battery conversion, reset line voltage monitor verification, address line bus continuity audit. | Logic State Analyzer, Desoldering Rework Station |
| Phase 3: Steppers & Optics | Infrared optical transmitter/receiver beam intensity check, stepper drive transistor curve analysis, reel basket friction assessment. | Infrared Optical Meter, Strobe Tachometer |
| Phase 4: Audio & Lighting | Dual-channel audio amplifier frequency response test (20Hz - 20kHz), LED driver current regulation check, cold cathode ballast replacement. | Audio Precision Analyzer, Digital Multimeter |
| Phase 5: Burn-in Testing | Continuous 72-hour operating cycle under elevated thermal ambient conditions to stress-test components and eliminate early failure risks. | Thermal Imaging Camera, Automated Cycle Sequencer |
Whether you have an IGT, Stern, Bally, or vintage electro-mechanical machine in need of circuit board recapping or mechanical overhaul, contact our Glasgow workshop for advice.
