$100 — Diagnostic and Troubleshooting Process
The first step to fixing a failing vacuum tube guitar amplifier involves figuring out the root causes of the failure. A reliable troubleshooting process for a failing vacuum‑tube guitar amplifier starts with simplifying the setup: test the amp using only a known‑good guitar, cable, and speaker to rule out external faul...

Electrolytic Capacitor Overhaul
Complete and thorough removal of all damaged, failed, malfunctioning, nonfunctional, burned, exploded, and leaking electrolytic capacitors. Installation of quality replacements to restore volume, reduce hum, improve stability and help protect your amp from further power supply issues. A common problem amongst vintage and modern Fender amps.

Circuit Board Component Replacement
When equipment failure starts at the component level, replacing entire boards isn’t always the smartest — or most cost-effective — solution. Our board-level electronic component replacement service delivers expert and precision repairs that restore functionality without unnecessary expense. Our technician specializes in identifying and replacing faulty components directly on circuit boards, including resistors, diodes, wiring and connectors. Using advanced diagnostic tools and industry-leading soldering techniques, we ensure reliable, long-lasting results while maintaining the integrity of your hardware.

Tube Bias Setting Service
Ensure optimal performance and reliability of your vacuum tube amplifier with our precision bias measurement and calibration service. Using calibrated instrumentation, we measure plate voltage, cathode current, and calculate plate dissipation to accurately set the quiescent operating point of the output stage. Bias is adjusted to manufacturer specifications—or fine‑tuned within safe operating limits—to achieve the correct balance between linearity, efficiency, and thermal stability. Proper biasing minimizes crossover distortion, prevents excessive plate dissipation, and ensures consistent transconductance across matched tube sets, ultimately delivering improved signal fidelity, stable operation, and extended tube lifespan.
