Still to verify: match the label on your item with the full official notice, including any exclusions, tables and photos. Some identifiers appear only on the agency website and are absent from this data feed. A missing field does not mean all versions are affected.
If your lot or date falls outside a stated range, this notice has not established that your item is affected. This is not a finding about other recalls or product safety.
2. Agency hazard and consumer action
CPSC reports: When the amplifiers are used with aftermarket metal base tubes, the bare metal can become electrified, posing a risk of serious injury or death from electrocution.
CPSC consumer action: Consumers should stop using the recalled amplifiers immediately and contact AudioLineOut for a free repair. Consumers should contact AudioLineOut at support@aloaudio.com for a prepaid shipping label to ship back the product for repair. Alternatively, consumers can utilize the originally supplied vacuum tubes.
Affected product: Studio Six Headphone Amplifiers
