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
When we received this Realistic STA-2100D, the receiver would not power on.
We inspected the power supply, amplifier and relay circuitry to diagnose the incoming no-power condition.

72-Hour Operational Test: We completed an extended 72-hour test to assess performance and stability.
Stereo Playback: Both amplifier channels were evaluated during final listening and functional testing.
