2. Istruzzjonijiet tas-Sigurtà

Please read and understand these safety instructions before operating the ampŻomm dan il-manwal għal referenza futura.

• Vol Għolitage: Dan amplifier contains high voltage components. Do not attempt to open the chassis or service the unit yourself. Refer all servicing to qualified personnel.
• Sors tal-Enerġija: Qabbad il- amplifer biss għall-volum speċifikat tal-provvista tal-enerġijatage indicated on the unit. Ensure the power cord is in good condition and properly grounded.
• Ventilazzjoni: Tiżgura ventilazzjoni adegwata madwar il- amplifier. Do not block ventilation openings. Avoid placing the unit on carpets or in enclosed spaces that could restrict airflow.
• Sħana: Vacuum tubes generate heat during operation. Keep the amplifier away from heat sources and direct sunlight. Allow sufficient cooling time before moving or storing the unit after use.
• Umdità: Tesponix il- ampProteġġi l-apparat mix-xita, l-umdità, jew umdità eċċessiva. Żomm il-likwidi 'l bogħod mill-unità.
• Oġġetti Barranin: Do not insert any objects into the amplifier's openings.
• Tindif: Skonnettja l-korda tal-enerġija qabel it-tindif. Uża drapp niexef u artab. Tużax prodotti tat-tindif likwidi jew aerosol.

• 6V6GT Power Tube: Jipprovdi l - amplifier's output power and contributes significantly to its tonal character, especially when overdriven.
• 5AR4 Rectifier Tube: Delivers tube rectification, which contributes to the amplifier's vintage "sag" and dynamic response.
• Celestion Speaker: A high-quality speaker chosen for its tonal characteristics and ability to complement the amplifier's tube sound.

5. Setup

1. Spakkjar: Neħħi bil-galbu amplifier from its packaging. Inspect for any signs of damage during transit.
2. Pjazzament: Poġġi l- amplifier on a stable, level surface. Ensure there is sufficient space around the unit for proper ventilation, especially at the rear and top where heat dissipates. Avoid placing it near other heat-generating equipment.
3. Konnessjoni tal-Enerġija: Tiżgura l- amplifier's power switch is in the "OFF" position. Connect the supplied power cable to the ampmad-daħla tal-AC tal-lifer u mbagħad ma' sokit elettriku ertjat.
4. Konnessjoni tal-Kitarra: Connect your guitar to one of the input jacks on the front panel using a high-quality instrument cable.
5. Settings Inizjali: Before powering on, set the Volume knob to its lowest setting.

6. Istruzzjonijiet Operattivi

1. Tixgħel: Flip the Power switch to the "ON" position. The indicator light will illuminate. Allow approximately 30-60 seconds for the tubes to warm up before playing.
2. Aġġusta tal-Volum: Slowly increase the Volume knob to your desired listening level. The JTA-05 is designed to produce clean tones at lower volumes and natural tube overdrive as the volume is increased.
3. Dynamic Tonal Control: Dan amplifier is highly responsive to your guitar's volume and tone controls.
   • To achieve a clean tone when the amplifier's volume is set higher (where it might typically break up), roll down your guitar's volume knob.
   • To return to an overdriven sound, simply roll your guitar's volume back up.
   • Experiment with your guitar's tone controls to further shape the sound.
4. Using Effects Pedals: The JTA-05 is designed to interact well with various effects pedals. Connect pedals between your guitar and the amplifier's input. Experiment with different pedal types (overdrive, distortion, modulation, delay) to find your preferred sound.
5. Itfi: Before turning off, it is recommended to lower the Volume knob. Then, flip the Power switch to the "OFF" position.

7. Manutenzjoni

• Tindif: Skonnettja l- amplifier from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use abrasive cleaners, solvents, or waxes.
• Sostituzzjoni tat-tubu: Vacuum tubes have a finite lifespan and will eventually need replacement. If you notice a decrease in performance, unusual noise, or a tube fails to glow, it may be time for replacement. Tube replacement should ideally be performed by a qualified technician due to high internal voltages. If replacing tubes yourself, ensure the amplifier is unplugged and allowed to cool completely. Handle tubes carefully, avoiding contact with the glass.
• Ħażna: Meta ma tkunx qed tużaha għal perjodi twal, aħżenha amplifier in a dry, temperature-controlled environment, away from direct sunlight and extreme temperatures.
