Burned in

Every tube is subjected to a controlled burn-in process at no additional cost prior to shipment. During burn-in, tubes are operated under load for an extended period to identify early failures and ensure stable, reliable performance. This process helps eliminate weak or unstable tubes before they ever reach your amplifier.
