This Oripure OA-C05 5W All Tube Guitar Amplifier Combo delivers warm tube response and straightforward tone shaping in a compact format well suited to home playing and lower-volume practice. Its two-stage preamp provides increased gain range, allowing the Gain and Volume controls to move from cleaner sounds into natural overdrive, while the single-ended output stage keeps the circuit simple and responsive.

This used amplifier has been fully tested and inspected to ensure reliable, enjoyable performance, making it a smart-value way to add a compact tube combo to your setup.

Features

The two-stage preamplifier is designed to provide a broad gain range, with separate Gain and Volume controls allowing players to shape everything from cleaner tones to more saturated overdrive. This makes the OA-C05 useful for practice, recording and players who want tube-driven breakup without excessive volume.

The single-ended power amplifier design emphasizes simplicity, stability and warm tube character. Its moderate 5 watt output makes it particularly practical for home use, where players can explore natural tube response at more manageable sound levels.

Bright and Warm voicing switches provide quick tonal changes, while Treble, Middle and Bass controls offer more detailed EQ adjustment. Together, these controls make it easier to tailor the amplifier to different guitars, pickups and playing styles.

Oripure places particular emphasis on the output transformer design, using layer-by-layer paper insulation to reduce stray capacitance and support a higher resonant frequency. Grain-oriented silicon steel is used in the transformer core to increase inductance and strengthen low-frequency response, contributing to clear highs and a fuller overall sound.

The OA-C05 is loaded with a custom 8 ohm internal speaker and uses a vintage-style open-back cabinet design for a more spacious, ambient response. A built-in carry handle makes the compact combo easy to move around the home, studio or rehearsal space.
