Инструкции за поставување
1. Отпакување и проверка
Внимателно отстранете го amplifier head from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. Retain the packaging for future transport or storage.

2. Tube Overview
The OA-H05 amplifier head utilizes three types of tubes for its operation:
- Предamp Цевка: 1 x 12AX7 (ECC83)
- Цевка за напојување: 1 x EL84
- Rectifier Tube: 1 x 6Z4

3. Поврзување со кабинет за звучници
Пред да го вклучите amplifier, ensure it is connected to a suitable speaker cabinet. The OA-H05 provides two output jacks:
- 8Ω (8 Ohm) Output: For speaker cabinets with an 8 Ohm impedance.
- 16Ω (16 Ohm) Output: For speaker cabinets with a 16 Ohm impedance.
Важно: Секогаш поврзувајте го amplifier to a speaker cabinet with the correct impedance before turning it on. Operating a tube amplifier without a load can cause severe damage to the output transformer.

4. Power Connection and Voltagд Избор
Connect the provided power cable to the MAINS input on the rear panel and then to a suitable power outlet. Ensure the MAINS SELECT switch is set to the correct voltage за вашиот регион (110V или 220V).

5. Влез за гитара
Поврзете ја гитарата со IN input jack on the front panel using a standard 6.35mm instrument cable. This is a 1-megohm high-impedance input.

Упатства за работа
1. Powering On and Standby
- Ensure all connections (speaker, power, guitar) are secure.
- Превртете го ON switch to the 'ON' position. The power indicator light will illuminate.
- Поставете го ЗАСТАНИ switch to 'OFF'. This allows the tubes to warm up with only the filaments heated and no high voltage applied. Wait for approximately 30-60 seconds for the tubes to reach operating temperature.
- After the warm-up period, flip the ЗАСТАНИ switch to 'ON' for normal operation.

2. Контроли надview
The OA-H05 features a single channel with the following controls:
- BRIGHT/WARM Switch: Toggles between a brighter, more articulate tone and a warmer, fuller tone.
- ВОЛУМЕН: Го контролира целокупното ниво на излез на ampживописен.
- ДОБИВКА: Ја прилагодува количината на предamp distortion and sustain. Higher gain settings produce more overdrive.
- БАС: Controls the low-frequency response.
- СРЕДЕН: Го контролира одговорот на средна фреквенција.
- ТРОБОВНО: Го контролира одговорот на висока фреквенција.
3. Tone Shaping
Experiment with the GAIN and VOLUME knobs to achieve various tones, from clean to overdriven. The BRIGHT/WARM switch and the 3-band EQ (BASS, MIDDLE, TREBLE) allow for extensive tonal customization to suit different musical styles and preferences.
На amplifier's single-ended output stage provides a distinct tonal character, often praised for its rich harmonics and dynamic response, especially when pushed into natural tube overdrive.

Одржување
1. Чистење
Избришете го amplifier's exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish. Ensure the ampОсвежувачот е исклучен од струја пред чистење.
2. Tube Replacement
Tubes have a finite lifespan and may need replacement over time. If you experience a decrease in performance, excessive noise, or inconsistent sound, it may be time to replace one or more tubes. Consult a qualified technician for tube replacement to ensure proper handling and biasing.
When replacing tubes, ensure the amplifier is completely powered off and unplugged, and allow sufficient time for the tubes to cool down. Handle new tubes carefully, avoiding touching the glass with bare hands, as oils can create hot spots and reduce tube life.
Решавање проблеми
Нема звук
- Check all power connections and ensure the amplifier is plugged into a working outlet.
- Потврдете дека ON и ЗАСТАНИ switches are in the correct positions.
- Ensure the speaker cable is securely connected to both the amplifier and the speaker cabinet, and that the speaker impedance matches the ampизлезот на лафијаторот.
- Check your guitar cable and guitar's volume knob.
- Allow adequate warm-up time for the tubes.
Weak or Distorted Sound (Unintended)
- Прилагодете го ДОБИВКА и ВОЛУМЕН controls. High gain settings will naturally produce distortion.
- Check the condition of your tubes. Worn-out tubes can cause weak or muddy sound.
- Ensure the speaker cabinet is functioning correctly.
- Review the Gain Spectrum Schematic to understand how tube amplifiers handle signal clipping compared to solid-state ampказните за слободни животи.

Прекумерна бучава или брмчење
- Ensure all cables are properly shielded and in good condition.
- Обидете се да го вклучите amplifier into a different power outlet or a power conditioner.
- Премести го ampдржете го ладилникот подалеку од други електронски уреди што можат да предизвикаат пречки.
- Faulty tubes can also introduce noise; consider having them checked.
