HICKOK Product Lines We Repair
Our engineers are trained on the full HICKOK product range. Below are the major product families we service.
Hickok Tube Testers
Precision vacuum tube test equipment including the legendary 539A, 6000, and 4150A series. Common repairs include faulty tube sockets, calibration drift, display panel failures, and power supply capacitor degradation affecting test accuracy.
Hickok Multimeters and Volt-Ohm Meters
Analog and digital multimeters used for field troubleshooting and bench testing. Typical faults include meter movement damage, internal relay failures, display degradation, and calibration errors caused by component drift over decades of use.
Hickok Power Supplies and Signal Generators
Laboratory-grade regulated power supplies and RF signal generators for component testing and system validation. Common issues: transformer insulation breakdown, filter capacitor failure, output voltage regulation loss, and frequency calibration shift.
Hickok Electronic Testers and Analyzers
Specialized electronic test equipment for semiconductors, capacitors, and complex circuit analysis. Repair challenges include measuring circuit calibration, sensor replacement, and restoration of safety features in high-voltage testing modules.
Hickok Vintage Industrial Instruments
Legacy bench instruments including oscilloscope comparators, frequency counters, and audio analyzers from the 1960s-1980s era still operational in Indian electronics maintenance labs. Repairs focus on CRT restoration, frequency reference recalibration, and electrolytic capacitor replacement.

Common HICKOK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HICKOK equipment arriving at our workshop.
- ✓Hickok tube tester socket corrosion and contact failure — Decades of use expose tube sockets to oxidation and carbon buildup from arcing. Poor connections prevent accurate tube bias measurement, causing false test results and equipment lockout.
- ✓Display panel degradation and meter movement stiction — Analog meters suffer mechanical stiction from dust, oil accumulation, and aging bearing wear. Needle stickiness prevents accurate deflection, producing unreliable voltage and resistance readings on Hickok multimeters.
- ✓Power supply voltage regulation loss and transformer insulation breakdown — Aging transformers and filter capacitors degrade, causing voltage sagging, ripple increase, and regulation failure. Internal insulation breakdown creates leakage current and fire risk in high-voltage supplies used for tube tester operation.
- ✓Calibration accuracy loss across frequency and voltage ranges — Component aging, reference oscillator drift, and thermal effects reduce Hickok instrument calibration accuracy over 20-30 years. Signal generators shift frequency; voltmeters diverge from nominal readings by 2-5% or more.
- ✓Relay chatter and intermittent range switching failures — Reed relays and selector switches in Hickok testers suffer contact pitting, corrosion, and mechanical wear. Intermittent switching prevents stable operation during critical test sequences.
- ✓CRT phosphor fading and beam deflection circuit failure — Oscilloscope CRTs lose brightness as phosphor ages; aging deflection capacitors and transformer insulation cause beam distortion, linearity errors, and eventual display failure on legacy Hickok test equipment.

Frequently Asked Questions — HICKOK Repairs
Do you repair Hickok equipment anywhere in India?+
Yes. Synchronics repairs the full Hickok product range — tube testers, multimeters, power supplies, signal generators, and vintage test instrumentation. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. Repairs completed at our 180+ engineer facility in Vadodara, Gujarat. Same-day courier dispatch upon completion.
Can you restore 1960s-1980s Hickok tube testers and vintage test equipment?+
Absolutely. Vintage Hickok 539A, 6000, and 52-series tube testers are specialty repairs for Synchronics. We replace aged capacitors, restore tube sockets, recalibrate measurement circuits, and test with known-good reference tubes. Many Indian audio shops, ham radio clubs, and industrial labs depend on us to keep their Hickok legacy equipment operational.
My Hickok multimeter reads inconsistently. What is the problem?+
Inconsistent readings typically point to meter stiction, dirty range selector relays, or capacitor leakage in the measurement circuit. Synchronics diagnoses the exact cause via full electrical and mechanical inspection. Most cases require meter movement cleaning, relay contact restoration, and capacitor replacement. We provide calibration proof on return.
Do you calibrate Hickok test equipment to factory standards?+
Yes. All Hickok repairs include full-range calibration against certified test standards. Voltage, current, resistance, and frequency measurements are verified across every function and range. We document all calibration data and provide a detailed test report with your repaired equipment, including confidence intervals.
How long does Hickok tube tester repair typically take?+
Standard Hickok repairs (socket cleaning, capacitor replacement, calibration) take 5-7 working days at Synchronics. Expedited service (3-4 days) available for urgent maintenance. We communicate progress updates; complex vintage restorations may require 10-14 days. All timelines provided upfront with no hidden fees.
How do I send my HICKOK 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 HICKOK 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 HICKOK 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 HICKOK 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.
