EICO Product Lines We Repair
Our engineers are trained on the full EICO product range. Below are the major product families we service.
EICO Tube Testers & Vacuum Tube Instruments
Analog vacuum tube test equipment including tube checkers, bias probes, and CRT testers. Common repair needs include faulty tube sockets, transformer breakdown, and electrolytic capacitor failure leading to measurement drift.
EICO Power Supplies & Regulated DC Sources
Precision regulated power supplies and bench DC sources for lab and production test. Failures include transformer saturation, rectifier tube failure, regulator stage malfunction, and output short circuit protection circuit faults.
EICO Analog Meters & Multimeters
Precision moving-coil analog multimeters and panel meters for measurement and calibration. Typical issues involve coil stiction, damping fluid degradation, meter shunt resistance drift, and selector switch contact corrosion.
EICO Signal Generators & Function Generators
Audio and RF signal generators producing sine, square, and triangle waves for testing audio circuits and RF equipment. Repair challenges include oscillator frequency drift, output attenuator pot wear, and distortion in output stage.
EICO Industrial Control Modules & Relay Panels
Vintage solid-state and relay-based control modules for production machinery automation. Common faults include relay contact deterioration, semiconductor aging, transistor leakage, and timing network drift.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common EICO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EICO equipment arriving at our workshop.
- ✓Electrolytic capacitor drying and voltage regulation failure — EICO vintage equipment from the 1950s-1980s uses electrolytic capacitors with 40-50 year lifespan. Drying causes output voltage ripple, regulation collapse, and transformer stress. Particularly common in bench power supplies and oscilloscopes.
- ✓Power transformer core saturation and open primary winding — Transformer primary windings fail due to insulation breakdown, age, or thermal stress from prolonged high-load operation. Saturation manifests as excessive primary current, audible hum, and failure to power secondary circuits.
- ✓Analog meter coil stiction and damping fluid degradation — Moving-coil meters in EICO multimeters and panel instruments suffer from viscous damping fluid breakdown (evaporation or gel formation) and mechanical friction in jeweled bearings. Results in slow pointer response, sluggish deflection, or locked needle.
- ✓Signal generator oscillator frequency drift and distortion — Aging resistors and capacitors in EICO function generators cause oscillator bias drift (frequency shift vs. temperature), output impedance change, and waveform distortion. RC timing networks drift 5-10% over decades.
- ✓Relay contact oxidation and switching intermittency — EICO relay-based controllers and sequence panels accumulate contact oxidation after decades of switching cycles. Low-current logic signals fail to switch contacts, causing intermittent control output and equipment malfunction.
- ✓CRT heater open circuit and display failure — Cathode ray tube filament/heater opens due to vibration fatigue or thermal cycling in EICO oscilloscopes and CRT testers. Results in complete loss of display or dim, unstable raster. Filament replacement requires CRT socket reconfiguration.

Frequently Asked Questions — EICO Repairs
Do you repair EICO equipment anywhere in India?+
Yes. Synchronics repairs the full EICO product range—analog instruments, test equipment, power supplies, signal generators, and vintage control modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Jaipur, and all tier-1 and tier-2 cities. All repairs are processed at our ISO 9001 facility in Vadodara, Gujarat. Turnaround is typically 10-15 working days.
What is your experience repairing EICO vintage tube equipment?+
EICO tube testers, oscilloscopes, and power supplies (1950-1980) are a specialty. Our engineers understand vintage transformer design, tube biasing networks, and long-obsolete component sourcing. We stock NOS (new old stock) tubes, paper-in-oil capacitors, and mil-spec resistors. All tube equipment undergoes 24-hour burn-in testing post-repair to confirm stability and safety.
Can you repair EICO instruments that are 40-50 years old?+
Absolutely. Age is not a barrier—mechanical design and circuit topology remain sound. The primary issues are capacitor drying, transformer insulation breakdown, and relay contact oxidation. Synchronics restores these instruments to original specifications by component replacement and functional re-alignment. We maintain detailed repair documentation for traceability and warranty.
Do you source replacement parts if EICO original parts are no longer available?+
Yes. For obsolete EICO parts, Synchronics sources modern equivalents (transformers, capacitors, tubes, semiconductors) that match or exceed original electrical specifications. All substitutions are documented in the repair report. Critical components—especially power transformers and CRT tubes—are sourced from trusted vendors to ensure reliability in Indian industrial environments.
What diagnostic testing do you perform on EICO equipment before repair?+
Every EICO unit receives comprehensive in-circuit diagnostics: AC megohm testing (high-voltage safety), component-level resistance and capacitance measurement, transformer primary/secondary continuity, relay contact resistance testing, and if applicable, oscilloscope output waveform analysis. Test results are logged and provided to you. This prevents hidden faults and ensures the unit is safe for operation in your facility.
How do I send my EICO unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a EICO drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on EICO repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your EICO unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
