Oripure OA-C05 5W tube guitar amplifier combo adopts two-stage pre-amplification to obtain greater gain. Controlled by the GAIN/VOLUME knob and can be adjusted to obtain timbre from clean to overdrive. The power amplifier adopts the single-ended mode (The single ended output stage), which has the characteristics of simplicity and stability, moderate power and warm tone. Two tone selection switches, BRIGHT /WARM , plus TREBLE, MIDDLE and BASS EQ adjustment, which can adapt to various needs.
The output transformerchooses the paper insulation for output transformers of each layer of insulating paper. The insulating paper has a lower dielectric constant. Make the transformer both have lower stray capacitance and higher resonant frequency. The high-frequency response of the transformer is great and the tone is transparent. The high-quality silicon steel sheet of Grain-Oriented Silicon Steel (35Z155-0.35) is used to obtain a larger inductance and enhance the low-frequency effect.
Gain Control: Lower gain settings produce clean tones, while higher gain settings result in overdriven tones. Standby Mode Control: The OFF position puts the amplifier in standby mode, with only the filaments heated and no high voltage applied, while the ON position is for normal operation
Preamp tube: 1 x 12AX7 (ECC83). Power tube: 1 x EL84. OA-C05 is lodaed with a custom 8Ω 1 x 10 inch internal speaker.
Outputs: 8Ω/16Ω. Jack: 1-megohm high-impedance 6.35mm input jack. Power Selector Switch: Switch between 110V and 220V power voltage. Built-in carry handle desige. Vintage Open-Back design to get a more”open” sound, rich with ambience and resonance.
