Professional diagnostic and board-level repair service for this Goring Kerr Tek 21 Power supply/control.
The Goring Kerr TEK‑21 is an SCR‑based power control board used to drive the high‑frequency output of a metal detector. Common failure points include worn or pitted SCR contacts, failed rectifier diodes, degraded electrolytic capacitors on the DC bus, and burnt‑out driver transistors that can cause loss of signal or overheating. First‑check diagnostics: verify input voltage and polarity to the board; inspect for visual signs of burn or corrosion on the SCR and diode assemblies; test continuity across the SCR terminals and measure output current under load to confirm proper switching. |
