Frank ---- Guitar amp repair, tube amp troubleshooting, and vintage amplifier restoration — straight from a real working bench. This channel features real-world guitar and tube amp diagnostics, repair walkthroughs, and full restorations. Most videos are client repair updates that double as how-to content, showing real-time troubleshooting, signal tracing, voltage checks, bias adjustments, cap jobs, parasitic oscillation fixes, noise chasing, and oscilloscope analysis. You’ll see practical fault-finding methods, component-level repairs, impedance testing, ESR testing, and clear, plain-language explanations of what failed, why it failed, and how it was properly fixed.
