## Long description

Vacuum Tube spare part for InLine AmpUSB HiFi DSD USB Audio DAC is a direct replacement tube designed for use in compatible AmpUSB DAC units. This spare part restores the tube-stage section of the DAC, returning characteristic harmonic coloration and the analog-like dynamics typical of vacuum tube amplification.

Advantages
This replacement vacuum tube provides the original tube-stage sonic characteristics, including warm harmonic overtones and smoother transient behavior compared with solid-state stages. It is manufactured to fit the AmpUSB tube socket and electrical requirements, enabling straightforward restoration of the device’s intended sound signature after component ageing or failure. The part supports typical operating conditions of tube stages in USB DAC applications and helps maintain consistent audio performance when installed correctly.
Suitable for
Repairing or restoring the tube stage of compatible InLine AmpUSB HiFi DSD USB Audio DAC units
Replacing aged or faulty vacuum tubes in tube-equipped USB DACs
Maintaining analog-like harmonic response and tube coloration in HiFi desktop audio setups
Key specifications
Tube type: dual triode vacuum tube (12AU7 / ECC82 form factor)
Physical format: standard small-signal octal/9-pin-compatible tube footprint used by the AmpUSB module
Intended function: preamplifier/tube stage replacement for USB DAC audio coloration and gain staging
Compatibility: designed for use in AmpUSB HiFi DSD USB Audio DAC devices with tube stage
How to use
Before replacing the tube, power off the DAC and disconnect all cables. Allow the device to cool and discharge residual voltages. Remove the old tube by gently pulling it straight out from the socket while supporting the surrounding chassis. Align the replacement tube with the socket pins and press down evenly until fully seated. Reconnect cables and power the unit on; perform a brief warm-up at low volume to stabilize operating conditions. If unsure about the procedure, consult the device service manual or a qualified technician for safe installation.
Usage recommendations
Operate the tube within the manufacturer’s specified ambient temperature and ventilation conditions. Avoid touching the glass envelope with bare hands; oils can create hot spots. Replace tubes in matched pairs when the device uses multiple tubes for balanced channels to maintain tonal consistency. Dispose of failed tubes according to local electronic waste regulations.
