3.2 குழாய் நிறுவல்
The AIYIMA T20 comes with two ECC83 tubes. Carefully insert each tube into its designated socket on the top panel of the preamplifier. Ensure the pins align correctly with the socket holes and apply gentle, even pressure until the tube is fully seated. Avoid forcing the tubes to prevent damage to the pins or sockets.

5. பராமரிப்பு
5.1 குழாய் மாற்று
The ECC83 vacuum tubes are user-exchangeable, allowing for sound customization. To replace tubes, ensure the unit is powered off and disconnected from the power source. Carefully grasp the existing tube and gently pull it straight up from its socket. Insert the new compatible tube (e.g., 12AX7-S, 12AX7B, 7025, 12AX7) ensuring correct pin alignment before gently pushing it into place.

5.2 Op-Amp மாற்று
The T20 also supports swapping op-amps for further sound customization. This procedure requires technical knowledge and should only be performed by experienced users. Ensure the unit is powered off and disconnected. Carefully remove the top cover of the unit. Locate the op-amp sockets on the PCB. Use an IC extractor tool to gently remove the existing op-amps (e.g., LME49720, OPA1612) and insert compatible replacements, paying close attention to orientation.

5.3 சுத்தம் செய்தல்
To clean the unit, power it off and disconnect it from the power source. Use a soft, dry cloth to wipe the exterior. Avoid using liquid cleaners or abrasive materials, as these may damage the finish or internal components.
6. சரிசெய்தல்
| பிரச்சனை | சாத்தியமான காரணம் | தீர்வு |
|---|---|---|
| சக்தி இல்லை | Power adapter not connected or faulty; incorrect power adapter used. | Ensure the DC12V power adapter is securely connected to both the unit and the power outlet. Verify that the correct DC12V adapter is being used. |
| ஒலி வெளியீடு இல்லை | Incorrect input selected; cables not connected properly; volume too low; unit in mute mode. | Check input selection (RCA/XLR). Verify all audio cables are securely connected. Increase volume. Ensure unit is not muted (double-click volume knob or use remote). Allow 20 seconds for soft-start warm-up. |
| Distorted or noisy sound | Loose tube or op-amp; faulty cables; interference; incorrect source signal. | Ensure tubes and op-amps are properly seated. Check audio cables for damage or loose connections. Try different cables. Ensure source signal is clean. |
| ரிமோட் கண்ட்ரோல் வேலை செய்யவில்லை | Batteries depleted or incorrectly inserted; obstruction between remote and unit. | Replace remote control batteries. Ensure there is a clear line of sight to the infrared receiving window on the unit. |
