Before Restoration

This Luxman SQ-38u was carefully inspected upon arrival to evaluate its mechanical, electrical, and cosmetic condition.

Our technicians inspected the exterior, controls, switches and connections, the installed tubes, the transformers, the internal chassis, the circuit boards, wiring and solder joints. The power-supply and signal capacitors were examined for bulging or leakage and measured against their original values (within 10% tolerance).

The inspection results were used to determine the work required for this specific unit.
