HQAUDIOS RESTORATION & TESTING
Professionally inspected, tested, and serviced. Aging or degraded components have been replaced where necessary to restore performance as close as possible to original factory specifications.

Before Restoration
We evaluated this Marantz 2330B’s power-supply and amplifier sections, including bridge rectifiers, capacitors, output transistors, circuit boards, and associated connections. We also inspected the tuner, illumination, operating controls, input/output jacks, and wood cabinet before carrying out service.

During Restoration
Capacitors: We inspected and measured capacitors in the serviced circuitry and replaced out-of-spec components with quality replacements of the correct electrical ratings.
Power Supply & Rectifiers: We serviced the power-supply circuitry, including attention to the bridge-rectifier components identified during inspection.
Power Amplifier Boards: We repaired affected amplifier circuitry, replaced selected transistors, and restored damaged or deteriorated areas of the circuit.
Circuit Boards & Solder Joints: We thoroughly cleaned the boards, inspected connection points, and reinforced solder joints in areas requiring attention.
Bias & DC Offset: We checked and adjusted the bias and DC offset on both amplifier channels in accordance with Marantz service specifications.
Lighting System: We replaced lighting components to restore the receiver’s illuminated display.
Switches & Controls: We cleaned and serviced the switches and control potentiometers to promote smooth, stable operation.
Input & Output Connections: We inspected and cleaned signal connections and speaker terminals.
FM Tuner: We inspected and serviced the FM tuner circuitry during the restoration process.
Wood Cabinet: We restored and refinished the cabinet surfaces while retaining the vintage character of the receiver.

After Restoration / Final Testing
Amplifier Operation: Both channels were evaluated following service for stable stereo playback.
Bias & DC Offset: Final operating adjustments were rechecked after service.
Controls & Connections: The serviced controls and signal paths were function-tested during normal operation.
FM Reception: FM tuner operation was tested following service.
Display Lighting: The renewed lighting system was checked during operation.
72-Hour Operational Test: We completed an extended 72-hour operational run to assess performance and stability after restoration.
Final Listening Test: We evaluated stereo playback with music as part of the receiver’s final functional check.
